실험 절차

To the stirred solution of 687 mg (2.4 mol) of di-tert-butyl cis-4-aminopyrrolidine-1,3-dicarboxylate (prepared according to J. Med. Chem. 2001, 44, 1192-1201) was added 2.1 mL of Hunig's base in 10 mL of N,N-dimethylformamide and 922 mg of 4-(2-methyl-quinolin-4-ylmethoxy)-benzenesulfonyl chloride hydrochloride. The solution was stirred at room temperature overnight. The N,N-dimethylformamide was removed in vacuo, and the residue was dissolved in 100 mL of chloroform. The chloroform solution was washed with water and saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified using flash chromatography on silica gel eluting with ethyl acetate/hexane to provide 929 mg (65% yield) of di-tert-butyl cis-4-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}sulfonyl)amino]pyrrolidine-1,3-dicarboxylate. MS: 598.4 (M+H)+
