実験手順

To a solution of tert-butyl (3S)-3-(2-aminoacetylamino)-1-pyrrolidinecarboxylate (3.07 g) in anhydrous tetrahydrofuran (45 ml), a solution of 4-nitrobenzyl [(4-nitrobenzyloxy)carbonylimino-pyrazol-1-ylmethyl]carbamate (5.38 g) in tetrahydrofuran (35 ml) was added under ice cooling, followed by stirring at room temperature for 30 minutes. Ethyl acetate was added to the reaction mixture. The resulting mixture was washed with water, an aqueous solution of potassium hydrogensulfate and saturated saline, dried over anhydrous magnesium sulfate and then concentrated by evaporation under reduced pressure. The residue was purified by chromatography through a silica gel column (ethyl acetate-dichloromethane), whereby the title compound (7.82 g) was obtained as an amorphous substance.
