Reaction Steps

To a solution of ethyl 2-carbamoyl-1H-indole-6-carboxylate (3.3 g, 14 mmol) in methanol (50 mL) was added 1 N aqueous sodium hydroxide (71 mL, 71 mmol). The reaction was stirred at room temperature for 17 hours. Then the reaction was acidified to pH 2-3 using 6 N aqueous hydrochloric acid. The resulting precipitate was collected by filtration and dried under vacuum to afford the title compound (2.97 g, 100%). −APCI (M−H) 203.4.
