Reaction Steps

N-{5-[2-(4-Aminophenyl)ethyl]-1,3-thiazol-2-yl}acetamide (100 mg), N,N′-bis(tert-butoxycarbonyl)-1H-pyrazole-1-carboxamidine (119 mg), N,N-dimethylformamide (1 ml) and tetrahydrofuran (2 ml) were combined under nitrogen atmosphere. The reaction mixture was stirred at 50° C. for 5.5 hours. After cooled to room temperature, the reaction mixture was concentrated in vacuo. The residue was purified by preparative silica gel column chromatography with n-hexane/ethyl acetate (1:2) as an eluent to give di-tert-butyl {[(4-{2-[2-(acetylamino)-1,3-thiazol-5-yl]ethyl}phenyl)amino]methylidene}biscarbamate (93.9 mg) as a colorless solid.
