実験手順

A solution of [(3R,4S)-4-(3,4-Dichloro-phenyl)-1-(piperidine-4-carbonyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester (50 mg, 0.10 mmol), 6-chloronicotinonitrile (21 mg, 0.15 mmol) in N-methylpyrrolidinone (0.5 mL) was treated with N,N-diisopropyl ethyl amine (52 μl, 0.30 mmol). The solution was stirred for 6 h at ambient temperature 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, heptane:ethyl acetate:methanol=80:20:0 to 0:90:10) afforded the title compound (52 mg, 86%) as an off-white foam. MS m/e: 596.2 [M]+.
