Reaction Steps

To a solution of methyl 1H-indazole-3-carboxylate (2.0 g, 11.4 mmol) in acetone (50 mL), were added potassium carbonate (1.6 g, 11.4 mmol) and (1-bromoethyl)benzene (2.2 g, 11.9 mmol). Then the mixture was refluxed for 12 hours. The reaction mixture was concentrated to give a residue. To the residue was added water (50 mL), extracted with dichloromethane (50 mL×3). The organic layers were combined, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give a residue. The residue was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=5:1) to afford two isomers.
