Procedure

9-Aminomethyl-4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine (20 g) was dissolved in chloroform (200 ml). tert-Butyl dicarbonate (13.4 g) was added under ice-cooling, and the mixture was stirred at room temperature for 4 hours. The mixture was washed with a saturated aqueous sodium hydrogen-carbonate solution and saturated brine, and dried over magnesium sulfate. The solvent was evaporated, and the residue was recrystallized from a mixed solvent of ethyl acetate and hexane to give 23.85 g of 9-(tert-butoxycarbonylaminomethyl)-4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine.
