実験手順
In pyridine (4.3 ml) was dissolved methyl 7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1-benzazepine-4-carboxylate (0.43 g). To the solution was added allyl chloroformate (0.23 ml), and the mixture was stirred at room temperature for 14 hours. To the mixture was added 4-dimethylaminopyridine (40 mg), and the mixture was stirred at room temperature for 2 hours. The reaction solution was added to water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried with magnesium sulfate. The solvent was removed under reduced pressure, and the resulting residue was purified with silica gel column chromatography (hexane/ethyl acetate→3/1) to give methyl 1-(allyloxycarbonyl)-7-[4-(2-butoxyethoxy)phenyl]-2,3-dihydro-1-benzazepine-4-carboxylate (0.30 g).
