Reaction Steps

To a solution of (5-chloro-3-methylsulfanyl-1H-indol-2-yl)-acetic acid methyl ester (0.252 g, 0.93 mmole) in ether (10 ml) was added 0.93 ml of a 1M solution of lithium aluminum hydride in ether at room temperature. The reaction mixture was stirred for 15 minutes, after which time sodium sulfate decahydrate (1 g) was cautiously added. The reaction mixture was stirred for an hour at room temperature, filtered, and the filtrate evaporated to dryness. The crude alcohol was purified by column chromatography (silica gel) using 7:3 hexane:ethyl acetate as the eluting solvent. The pure 2-(5-chloro-3-methylsulfanyl-1H-indol-2-yl)-ethanol was isolated as a pale solid (0.191 g, 84% yield).
