실험 절차
5-Trifluoromethylindole (D5, 1.0 g, 0.0057 mole) in glacial acetic acid (25 ml) was treated with sodium cyanoborohydride (1.7 g, 0.027 mole) under argon and stirred at room temperature for 2 hours. The mixture was poured into water (200 ml), basified with 40% aqueous sodium hydroxide solution, extracted into DCM, dried (Na2SO4) and evaporated in vacuo. The residue was chromatographed on silica gel eluting with 20% ethyl acetate/60-80° petroleum ether to afford the title compound (0.45 g, 45%) as a pale yellow oil.
