実験手順
To a solution of 7-(4-ethoxyphenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylic acid (180 mg) in THF (10 ml) were added at room temperature oxalyl chloride (0.09 ml) and a drop of DMF, and the mixture was stirred for 1 hour. The mixture was concentrated under reduced pressure, and the residue was dissolved in THF (10 ml). The solution was added dropwise at 0° C. to a solution of 4-[N-(4,4-ethylenedioxycyclohexyl)-N-methylaminomethyl]aniline [0.153 g (0.553 mmol)] and triethylamine (0.14 ml) in THF (5 ml), and the mixture was stirred at room temperature for 16 hours. To the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with magnesium sulfate. The solvent was evaporated under reduced pressure to give crude crystals, which were recrystallized from ethanol/diisopropylether to give colorless crystals of 7-(4-ethoxyphenyl)-N-[4-[N-(4,4-ethylenedioxycyclohexyl)-N-methylaminomethyl]phenyl]-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 18) (187 mg).
