Reaction Conditions

Reaction Steps

6-Bromo-1H-indazol-4-amine (available from Sinova, 300 mg, 1.42 mmol) was dissolved in THF (7.5 ml) and the mixture cooled to 0° C. Sodium hydride (62 mg, 1.56 mmol) was then slowly added. The mixture was stirred for 15 minutes, then methyl iodide (221 mg, 1.56 mmol) was added and stirring continued at 0° C. for 3 h. The reaction mixture was quenched by careful addition of methanol (2 ml), then water (10 ml), then extracted into ethyl acetate and the organic layer was concentrated in vacuo. The residue was purified by column chromatography on silica eluting with a gradient of 0-50% ethyl acetate in cyclohexane. Fractions containing desired product were combined and concentrated in vacuo to afford the title compound (48 mg).
