実験手順: A mixture of 4-{[4-(3-chloropropoxy)-2-methylphenyl]-methyl}-5-isopropyl-3-(2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyloxy)-1H-pyrazole (1.34 g), 3-benzylaminopropionamide (0.73 g), sodium iodide (0.24 g), ethanol (6 mL) and acetonitrile (6 mL) was stirred at 70° C. for 2 days. To the reaction mixture was added sodium iodide (0.2 g), and the mixture was further stirred at 75° C. for 24 hours. The reaction mixture was poured into 1 mol/L hydrochloric acid, and the resulting mixture was extracted with ethyl acetate. The extract was washed with water, a saturated aqueous sodium hydrogen carbonate solution and brine, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/5−dichloromethane/methanol=15/1) to give the title compound (0.97 g). the mixture was further stirred at 75° C. for 24 hours the resulting mixture was extracted with ethyl acetate The extract was washed with water a saturated aqueous sodium hydrogen carbonate solution and brine, and dried over anhydrous sodium sulfate The solvent was removed under reduced pressure the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/5−dichloromethane/methanol=15/1)

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of acrylamide (32 g) in ethanol (450 mL) was added benzylamine (59 mL), and the mixture was stirred at 60° C. overnight. The reaction mixture was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/1-dichloromethane/methanol=50/1) to give the title compound (73.2 g). The reaction mixture was concentrated under reduced pressure the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/1-dichloromethane/methanol=50/1)
