反应详情

5.5 ml 1 M borane-tetrahydrofuiran complex was slowly added to a solution of 1 g (5.5 mmole) 4-(methylmercapto)phenyl acetic acid in 5 ml tetrahydrofuran at −10° C. The reaction mixture was allowed to reach room temperature and the reaction was followed by TLC. After completion 10 ml methanol was added and the solvents were evaporated. Diethyl ether and 2 M sodium hydroxide was added, the phases were separated, the organic phase was dried, filtered and evaporated in vacuo to give 0.8 g (yield 84.4%) of 2-[4-(methylmercapto)phenyl]-1-ethanol.
