Reaction Steps

To a solution of ethyl 7-fluoro-4-methoxy-1H-indole-2-carboxylate (1.00 g, 4.22 mmol) in ethanol was added KOH (473 mg, 8.43 mmol). The reaction was stirred at room temperature for 12 hours, cooled to 0° C. and acidified with 1 N HCl. The mixture was extracted with EtOAc and CH2Cl2. The combined organic extracts were dried over Na2SO4, filtered and concentrated to afford the title compound (550 mg, 62%).
