实验步骤: To a solution of rac-{(3R,4S)-4-(3,4-Dichloro-phenyl)-1-[1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-methyl-carbamic acid chloride (250 mg, 0.50 mmol) in THF (1 mL) was added (2-cyclopropyl-ethyl)-methyl-amine (99 mg, 1.0 mmol) and N,N-diisopropyl ethyl amine (256, 1.50 mmol). The solution was irradiated in the microwave for 900 sec. at 130° C. before it was diluted with ethyl acetate (15 mL) and washed with an aqueous solution of sodium carbonate (1 M, 15 mL). The organic layer was separated and washed with brine (15 mL) and the aqueous layers were extracted with ethyl acetate (20 mL). The combined organic layers were dried over sodium sulfate and concentrated. Purification by chromatography (SiO2,ethyl acetate:methanol=100:0 to 85:15) afforded the title compound (202 mg, 72%) as a white foam. MS m/e: 563.4 [M]+.
