실험 절차

Carbazole 46 (0.4 g, 1.81 mmol) was dissolved in CH2Cl2 (7 mL), then NaH (0.22 g, 5.50 mmol) was added. The mixture was stirred at room temperature for 5-10 min, and 2-(2-chloroethyl)-1-methylpyrrolidine hydrochloride (0.4 g, 2.17 mmol) was added. The mixture was heated to 60° C. and kept at this temperature for 4 h (TLC monitoring, eluent: CHCl3-MeOH, 9:1). The resulting mixture was poured into water. The product was extracted with ethyl acetate, dried over Na2SO4, and evaporated. The residue was triturated with ether. The precipitate was filtered off. Yield of 65: 0.365 g (61%)—S-isomer and 0.336 g (55%)—R-isomer.
