Participants

Reaction Steps

To the solution of ethyl 3-(2-methylpyridin-4-yl)-1-trityl-1H-indazole-5-carboxylate (260 mg, 0.5 mmol) in THF (5 mL) was added LiOH (1M, 2 mL). The reaction mixture was stirred at room temperature for overnight. HCL was added to adjust the pH to 4-5 and ethyl acetated was added. The extract was washed with water (10 mL0 and dry over sodium sulfate and concentrated to give the desired product in 95% yield.
