Reaction Steps

The title compound was prepared by reacting 4-(2-chlorophenyl)-2-iodo-9-methyl-6H-thieno-[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine with 1,3-dihydro-1-phenyl 3-(2-propynyl)-2H-benzimidazol-2-one under the conditions used in Example 37. The product was isolated by chromatography over the 50-fold amount of silica gel using 5% (v/v) of ethanol in methylene chloride. The clean fractions were combined and evaporated and the residue was crystallized from methanol/ethyl acetate and recrystallized from methanol to yield off white crystals of 1-{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 }-1,3-dihydro-3-phenyl-2H-benzimidazol-2-one with m.p.176°-179°. These crystals contained 0.66 mol of water according the analytical data.
