실험 절차

A solution of N-(1-{(3R)-3-[(tertbutoxycarbonyl)amino]piperidin-1-yl}-2,2-dicyanovinyl)glycine ethyl ester (300 mg), 2-chlorobenzyl bromide (0.15 ml) and potassium carbonate (330 mg) in acetone (4 ml) was stirred at 25° C. for 24 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with an aqueous sodium chloride solution, dried over sodium sulfate and then filtered and the filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column chromatography (hexane/ethyl acetate=5/1 to 1/1) to obtain the title compound (340 mg) as a white amorphous substance.
