Participants

Reaction Steps

To a mixed solution of methanol (10 mL) and water (2 mL), methyl 2-methyl-1-(pyrimidin-5-ylmethyl)-1H-indole-3-carboxylate (110 mg, 0.39 mmol) and potassium hydroxide (50 mg, 0.98 mmol) was added. The mixture was stirred at reflux for 12 hours. Then the reaction mixture was acidified by hydrochloric acid aqueous solution (1N) to adjust pH=6 and extracted with dichloromethane (10 mL*3). The organic layers were combined and concentrated to give 1-isopropyl-2-methyl-1H-indole-3-carboxylic acid (60 mg, 58%).
