3 supporting information [ 4,4-Dimethyl-3,4-dihydropyrido[2,3 :3,4]pyrazolo[1,5-a][1,3,5]triazin-2-amine ethanol monosolvate Anton V. Dolzhenko, Geok Kheng Tan, Anna V. Dolzhenko, Lip Lin Koh and Wai Keung Chui S1. Comment The pyrazolo[1,5-a]triazine heterocyclic system has been recognized as a template for the construction of new potential therapeutic agents (Dolzhenko et al., 2008). However data on pyrido[2,3 :3,4]pyrazolo[1,5-a][1,3,5]triazines are limited and no details on their structure are available. Herein, we report molecular and crystal structure of 4,4-dimethyl-3,4-dihydropyrido[2,3 :3,4]pyrazolo[1,5-a][1,3,5]triazin-2-amine, which crystallizes with a ethanol molecule to give the title compound, C 10 H 12 N 6.C 2 H 5 OH (Fig. 1 & 2). This molecule has a close structural resemblance with some known dihydrofolate reductase inhibitors such as antimalarial drug cycloguanil and its fused analogue (Toyoda et al., 1997) (Fig. 3). Due to annular tautomerism, four tautomeric forms are theoretically possible for the compound (Fig. 4). Similarly to the previously reported (Dolzhenko et al., 2007b) related fused gem-dimethyl substituted amino-1,3,5-triazine, the compound exists in the crystal as a tautomer with the labile hydrogen atom located at the triazine nitrogen atom adjacent to the sp 3 hybridized carbon atom. The heterocyclic system is nearly planar (with r.m.s. deviation of Å) with a distortion at the triazine ring. The triazine ring adopts the conformation best described as an intermediate between a flatten twist boat and a half-boat with atoms C-8 and N-4 at the bow and the stern. The angle between the geminal flagpole and bowsprit methyl groups is (14). The N4 C7, N5 C7 and N6 C7 bond distances are similar suggesting guanidine-like electron delocalization in the N4 N6/C7 fragment of the molecule. In the crystal, the molecules form centrosymmetric dimers connected by the N HO and O HN hydrogen bonds between the amino group N6 H6A, ethanol molecule and the triazine N4 atom making a R 44 (12) graph-set motif (Bernstein et al., 1995). Another hydrogen atom of the amino group N6 H6B and the hydrogen atom at the endocyclic N5 atom act as hydrogen donors forming N HN contacts with the pyrazole and pyridine N2 and N1 atoms, respectively. They arrange molecules into the running along a [010] axis C(7)C(7) chains with the R 22 (8) binary graph-set motif. S2. Experimental 4,4-Dimethyl-3,4-dihydropyrido[2,3 :3,4]pyrazolo[1,5-a][1,3,5]triazin-2-amine was prepared by the cyclocondensation of pyrazolo[3,4-b]pyridin-3-guanidine with acetone similarly to the previously described methods (Dolzhenko et al., 2007a; Dolzhenko et al., 2009). 1H-Pyrazolo[3,4-b]pyridin-3-guanidine (0.88 g, 5.0 mmol) and piperidine (0.30 ml, 3.0 mmol) were heated in acetone (30 ml) under reflux for 10 h. After cooling, the product was filtered and washed with acetone. Yield: 0.89 g (82%). The crystals suitable for crystallographic analysis were grown by recrystallization from ethanol. m.p. 559 K. sup-1

Refinement All C-bound H atoms were positioned geometrically and included in the refinement in riding-motion approximation [0.95 Å for CH of pyridine ring, 0.98 Å for methyl groups, and 0.99 Å for methylenic protons; U iso (H) = 1.2U eq (C py ), U iso (H) = 1.5U eq (C Me ) and U iso (H)= 1.2U eq (C methylenic )] while the N-bound H atoms were located in a difference map and refined freely. The ethyl group of ethanol molecule was disordered into two positions with occupancy ratio of 78:22.

All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wr and goodness of fit S are based on F 2, conventional R-factors R are based on F, with F set to zero for negative F 2. The threshold expression of F 2 > σ(f 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
