Reaction Steps

To a mixture of methyl 6-chloro-5-[3-fluoro-4-(3-hydroxypropoxy)phenyl]-1H-indole-3-carboxylate (85 mg, 0.23 mmol) in methanol (5 mL) and water (2 mL) was added sodium hydroxide (90 mg, 2.3 mmol). The reaction mixture was heated at 70° C. and stirred for 24 hours. The mixture was acidified by 1N HCl to pH 4 and extracted with ethyl acetate (10 mL×3). The combined organic layers was dried over sodium sulfate, filtered, and concentrated in vacuo to give a brown residue. It was purified by preparative HPLC to give the title compound (31 mg, 52% yield) as a white solid.
