Procedure

To a solution of (S)-methyl 6-chloro-5-(3-methoxy-4-(pyrrolidin-2-ylmethoxy)phenyl)-1H-indole-3-carboxylate hydrochloride (22.6 mg, 0.050 mmol) in methanol (0.26 mL) was added tetrahydrofuran (0.26 mL) and sodium hydroxide (1N in water, 0.26 mL, 0.26 mmol). The mixture was then sealed and heated to 65° C. After 41 h, the mixture was allowed to cool to 23° C., concentrated in vacuo, diluted with water (1 mL), then acidified to pH 7.5 with hydrochloric acid (1N in water). The solid was filtered and purified by reverse phase HPLC to provide the title compound. MS (ES+) 401.2 (M+H)+. HPLC retention time: 1.44 min, Waters XBridge C18, 5 μm, 4.6×50 mm, 0.03% NH4OH, 5-95% acetonitrile in water gradient over 4.0 min, hold at 95% acetonitrile in water to 5.0 min, flow 2.0 mL/min.
