Reaction Steps

9-Aminomethyl-4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine (1.07 g) was dissolved in chloroform (50 ml). 3-Methylphenyl isocyanate (0.44 g) was added at room temperature, and the mixture was stirred for 3 hours. The reaction mixture was concentrated, and crystallized from ethyl acetate. The crude crystals were recrystallized from methanol to give 1.47 g of N-(4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepin-9-ylmethyl)-N'-(3-methylphenyl)urea.
