실험 절차
The indole (D2) (67.63 g, 0.315 mol) in glacial acetic acid (500 ml) was treated with sodium cyanoborohydride (40 g, 0.637 mol) portionwise at room temperature with stirring. After 3 h at room temperature the reaction mixture was diluted with water (500 ml) and basified with 40% aqueous NaOH with cooling. The mixture was then extracted with dichloromethane (3×500 ml) and the combined extracts were dried (Na2SO4) and evaporated to give the title compound (67.73 g, 99%) as an off-white solid.
