실험 절차

To a solution of 5-(trifluoromethyl)indan-1-one (0.7 g, 3 mmol) in THF (5 mL) cooled in an ice bath was added sodium borohydride (0.1 g, 3 mmol) followed by MeOH (1 mL). After being stirred for 30 min, the reaction was quenched with aqueous NaHCO3. The resulting solution was extracted with EtOAc twice. The extracts were washed with brine, dried (MgSO4), filtered and, concentrated. The crude material was purified by flash chromatography on silica eluting with 20% EtOAc/hexane to afford the desired product (0.65 g, 92%) as an oil. LC/MS calculated for C10H9F3O: (M+H)+ 203; found 185.1 (M+H—H2O)+.
