실험 절차

N-hydroxybenotriazole (HOBt) (0.427 g) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (WSC) (0.535 g) were added to an ice-cooled mixture of the compound (1.0 g) obtained in Example 18B, (1,2,4-triazol-1-yl)acetic acid (0.325 g) and N,N-dimethylformamide (DMF) (20 ml), the mixture was stirred at room temperature for 8 hours, poured over water and extracted with ethyl acetate. The ethyl acetate layer was washed with water, dried (MgSO4) and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography and eluted with ethyl acetate-methanol (20:1, v/v) to yield 7-benzyl-3-chloro-4-(3,4-dimethoxyphenyl)-5,6,7,8-tetrahydro-2-(1,2,4-triazol-1-ylacetylaminomethyl)thieno[2,3-b:5,4-c']dipyridine (0.55 g, 50%), which was then recrystallized from ethyl acetate-hexane to yield a colorless powder having a melting point of 101 to 102° C.
