4-(2-chlorophenyl)-2-iodo-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine → 2-{3-[4-(2-Chloro-phenyl)-9-methyl-6H-1-thia-5,7,8,9a-tetraaza-cyclopenta[e]azulen-2-yl]-prop-2-ynyl}-3,4-dihydro-2H-isoquinolin-1-one

Reaction Steps

The title compound was synthesized by coupling 4-(2-chlorophenyl)-2-iodo-9-methyl-6H-thieno-[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine with 3,4-dihydro-2.(2-propynyl)1(2H)-isoquinolinone [ref. W. Schneider et al. Arch. pharm., 291, 560 (1958)]under the conditions described in EXAMPLE 37. The product was isolated by chromatography over the 50-fold amount of solica gel using tetrahydrofuran/hexane 4:1 for elution. The clean fractions were combined and evaporated and the residue was crystallized from ethyl acetate to give colorless crystals of 2-{3-[4-(2-chlorophenyl) 9 methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-2.yl]-2-propynyl}-3,4-dihydro-1(2H)-isoquinolinone with m.p. 164°-166°.
