Procedure

To a solution of 7-(4-morpholinophenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxylic acid hydrochloride (200 mg) and 1-hydroxybenzotriazole (0.12 g) in DMF (5 ml) was added at room temperature 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.18 g), and the mixture was stirred for 1 hour. To the mixture was added a solution of 4-[N-(4,4-ethylenedioxycyclohexyl)-N-methylaminomethyl]aniline (0.19 g) and triethylamine (0.2 ml) in DMF (3 ml), and the mixture was stirred for 64 hours. The mixture was concentrated under reduced pressure, and to the residue was added water. The mixture was extracted with ethyl acetate, and the organic layer was washed with saturated brine and dried with magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified with column chromatography (ethanol/ethyl acetate=1:1) to give yellow crystals of N-[4-[N-(4,4-ethylenedioxycyclohexyl)-N-methylaminomethyl]phenyl]-7-(4-morpholinophenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (Compound 15) (119 mg).
