Reaction Steps

A solution of 7-(2,4-dichloro-phenyl)-2-methyl-2H-indazole-3-carboxylic acid methyl ester (35b; 0.050 g, 0.15 mmol) in 4 mL of a 2 M solution of methylamine in methanol was stirred for 6 d, then concentrated to a white solid. Column chromatography (0→45% EtOAc/hexanes) afforded of 7-(2,4-dichloro-phenyl)-2-methyl-2H-indazole-3-carboxylic acid methylamide (35d; 0.044 g; 88%).
