The obtained reaction mixture was stirred at room temperature for 10 hours. The produced white solid was filtrated, to obtain N-(benzo[d]thiazole-2-yl)-1H-imidazole-1-carboxamide (0.261 g, 54%). N-(benzo[d]thiazole-2-yl)-1H-imidazole-1-carboxamide (30 mg) was dissolved in 5 ml of tetrahydrofuran, and 11.1 mg of 2-aminoacetonitrile and then 29 μl of acetic were added thereto in a dropwise manner. The obtained reaction mixture was stirred at 30° C. for 18 hours, to produce N-(benzo[d]thiazole-2-yl)-2-cyanoacetamide (10 mg) in a light brown solid phase
