실험 절차

(S)-tert-Butyl 2-(3-(perfluorophenoxysulfonyl)propyl)pyrrolidine-1-carboxylate (2.8 g, 6.099 mmol) and 1-(1-methylpiperidin-4-yl)piperazine (1.676 g, 9.148 mmol) were dissolved in tetrahydrofuran (40 ml), 1,8-diazabicyclo[5.4.0]undec-7-ene (2.7 ml, 18.297 mmol) was added under an inert gas and the mixture was refluxed for 2 h. Ethyl acetate and saturated sodium bicarbonate solution (50 ml of each) were added, the phases were separated and the aqueous phase was extracted with ethyl acetate (2×50 ml). The combined organic phases were washed with saturated sodium bicarbonate solution (40 ml), dried over sodium sulfate and concentrated in vacuo. The crude product was purified by column chromatography (silica gel) with ethyl acetate/methanol/methylene chloride/ammonia (25% aq) (300:100:50:1). Yield: quantitative
