To a solution of methyl 5-(trifluoromethyl)thiophene-3-carboxylate (523 mg) in THF (1 ml)-MeOH (1 ml) was added NaBH4 (2.2 g) at room temperature, and the reaction mixture was stirred at 60° C. for 3 h. The reaction mixture was quenched with water, and extracted with EtOAc. The extract was washed with brine, dried over MgSO4, concentrated and purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (449 mg) as a pale yellow oil.
