Reaction Steps

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 (1 N 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 (1 N 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.
