実験手順

6-Bromo-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-amine (2.25 g, 7.59 mmol) was dissolved in DCM (40 ml) and DIPEA (2.85 ml, 16.34 mmol) was added. 1-(1-methylethyl)-1H-pyrazole-5-carbonyl chloride (1.41 g, 8.17 mmol) in DCM (10 ml) was added and the mixture left to stir at room temperature overnight. Water (50 ml) was added and the mixture vigorously stirred. The DCM layer was passed through a hydrophobic frit and evaporated to dryness. The material was combined with that obtained from a previous smaller scale reaction carried out in an identical manner but starting with 6-bromo-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-amine (0.2 g, 0.675 mmol). The combined crude materials were purified by chromatography on silica using a 50 g cartridge and eluting progressively with DCM, then 1-4% methanol in DCM. Product containing fractions were combined and evaporated to dryness to afford the title compound (2.8 g).
