실험 절차
4-Methoxy-benzenesulfonyl chloride (3.00 g, 14.52 mmol) was slowly added to a solution of pyrrolidine (5.15 g, 72.6 mmol) in CHCl3 (15 mL) with stirring at 0° C. The reaction mixture was allowed to warm up to room temperature and then stirred for 1 hour. After that the reaction mixture was concentrated in vacuo. The residue was dissolved in toluene and washed with aqueous H3PO4 solution, and then aqueous KHCO3 solution. The organic phase was dried with Na2SO4, and filtered. The solvents were removed in vacuo and the residue crystallized from ether and heptane to provide the title compound (3.21 g, m.p. 88-89° C.).
