Procedure

Benzyl (R)-4-amino-4-(4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepin-9-yl)butanoate di-p-toluenesulfonate (2.0 g) and 2-methoxyphenyl isocyanate (0.34 ml) were dissolved in DMF (20 ml). Triethylamine (0.97 ml) was added and the mixture was stirred. Water was added to the reaction mixture. The mixture was washed with an aqueous citric acid solution, saturated brine, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography using ethyl acetate as an eluent to give 1.19 g of benzyl (R)-4-(4-(2-chlorophenyl)-2-ethyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepin-9-yl)-4-(3-(2-methoxyphenyl)ureido)butanoate.
