実験手順

4-(2-Chlorophenyl)-2-ethyl-9-methyl-6H-thieno[3,2-f] [1,2,4]triazolo[4,3-a] [1,4]diazepine (702 g) was suspended in a mixed solvent (4.9 l) of ethanol and water (9:1), and p-toluenesulfonic acid monohydrate (1165 g) was added. The mixture was stirred at 80° C. for 1.5 hours. The mixture was concentrated to about 2.5 l by evaporating the solvent under reduced pressure, and ethyl acetate (4 l) was added. The reaction mixture was filtered to give crystals, and the crystals were washed with ethyl acetate and ethanol and dried to give 1214 g of 3-aminomethyl-4-(3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl)-5-methyl[1,2,4]triazole di-p-toluenesulfonate.
