In the title compound, C12H10ClN5·CH3OH, the indazole ring system and the pyrimidine ring make a dihedral angle of 23.86 (4)°. In the crystal, the components are linked by N—H⋯O and O—H⋯N hydrogen bonds into chains propagated in [010]. Intermolecular π–π interactions [centroid–centroid distances = 3.6404 (9), 3.6725 (9) and 3.4566 (9) Å] between the rings of neighbouring chains also stabilize the crystal packing.

To a stirred solution of the 2-methyl-2H-indazol-6-amine (10 g, 0.07 mol) and NaHCO3 (12 g, 0.14 mol) in ethanol (250 ml) was added 2,4-dichloropyrimidine (12 g, 0.08 mol) at room temperature. After the reaction was heated for four hours, the suspension was cooled to room temperature, filtered and washed thoroughly with ethyl acetate. The filtrate was concentrated under reduced pressure to get off-white solid as crude product. The solid was dissolved in methanol 40 ml at 293 k, then colourless crystals were generated slowly.
C-bound H atoms were geometrically positioned (C—H 0.95–0.98 Å), and refined as riding with Uiso = 1.2–1.5Ueq(C). The H atoms of N—H and O—H were found from difference map and isotropically refined.

Geometry. 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 F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In continuation of our studies of derivatives of antitumor agent pazopanib (Qi et al., 2010), we obtained the title compound (I).
In (I) (Fig. 1), all bond lengths and angles are normal and correspond to those reported by Qi et al. (2010). In N-(2-chloropyrimidin-4-yl)-2-methyl-2H-indazol-6-amine (M) molecule, the indazole and pyrimidin fragments form a dihedral angle of 23.86 (4)°.
In the crystal structure, M and methanol molecules are linked by N—H···O and O—H···N hydrogen bonds (Table 2) into chains propagated in [010]. Intermolecular π—π interactions (Table 1) between the rings from the neighbouring chains stabilize the crystal packing.
