実験手順
The above 1-(4-trifluoromethoxyphenyl)-3,4-dihydro-isoquinoline (0.40 g, 1.4 mmol) was dissolved in methanol (20 mL) and sodium borohydride (0.08 g, 2.1 mmol) was added slowly. The reaction mixture was stirred at room temperature for 2.5 hours. The mixture was evaporated in vacuo, redissolved in 1 N NaOH (20 mL) and extracted with dichloromethane (50 mL). The organic phase was dried (MgSO4), filtered and evaporated in vacuo. The remaining oil (0.35 g) was purified by column chromatography on silica gel eluting with a mixture of dichloromethane and methanol (9:1). This afforded 0.56 g (56%) of the title compound.
