Versuchsvorschrift

A mixture of the compound obtained in Example 115 (104 mg), benzylamine (24 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (WSC, 42 mg), 1-hydroxy-1H-benzimidazole monohydrate (HOBt, 34 mg) and DMF (3 ml) was stirred at room temperature for 10 hours. The reaction mixture was poured into water. The mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water and dried (MgSO4) and the solvent was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography to obtain N-benzyl-2-(4-{3-chloro-2-[(2,5-dioxo-1-pyrrolidinyl)methyl]-7-oxido-5,8-dihydro-6H-thiopyrano[4′,3′:4,5]thieno[2,3-b]pyridin-4-yl}phenoxy)acetamide from the fraction eluted with ethyl acetate-methanol (6:1) (70 mg, 57%). It was recrystallized from THF-hexane. Colorless prisms. Melting point 220–221° C.
