実験手順

tert-Butyl (3R,5S)-3-(morpholin-4-ylcarbonyl)-5-{[(2-nitrophenyl)sulfonyl]amino}piperidine-1-carboxylate (4.68 g) was dissolved in DMA (20 ml), cesium carbonate (9.18 g) and 1-iodopropane (1.83 ml) were added, and the mixture was stirred at 60° C. for 4 hr. The reaction mixture was diluted with water, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (3:7-10:0) was concentrated under reduced pressure to give the object product (4.02 g).
