Procedure
A mixture of the compound obtained in Example 37 (500 mg), morpholine (99 mg), N,N-dimethylaminopyridine (13 mg), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (197 mg), and DMF (10 ml) was stirred at room temperature for 10 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The ethyl acetate layer was washed with water, dried (MgSO4), and then evaporated under reduced pressure to remove the solvent. The residue was subjected to column chromatography on silica gel to obtain 1-{[3-chloro-4-(4-methoxyphenyl)-7-[(4-morpholinyl)carbonyl]-5,6,7,8-tetrahydro[1]benzothieno[2,3-b]pyridin-2-yl]methyl}-2,5-pyrrolidinedione (2.6 g, 92%) from the eluates with ethyl acetate. It was recrystallized from chloroform-hexane. Colorless prisms. Melting point 170–171° C.
