To a solution of 1-(4-aminocyclohexane-1-ylcarbonyl)-4-(6-chloronaphthalene-2-sulfonyl)piperazine hydrochloride (220 mg) and triethylamine (232 mg) in methanol (10 ml)-tetrahydrofuran (10 ml) was added N,N′-di-tert-butoxycarbonyl-S-methylisothiourea (135 mg) and the solution was stirred at 40° C. for 24 hours. The reaction solution was concentrated, and the residue was purified with silica gel column chromatography (hexane:ethyl acetate=1:2) to give a colorless solid of the title compound (170 mg).
