반응 단계
The procedure described in Example 3 was followed, using 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine trihydrochloride (3.77 g; 10 mmole), tetrahydrofuran (50 ml), triethylamine (4.2 ml; 30 mmole) and 4-nitrophenyl isocyanate (1.64 g; 10 mmole). Recrystallization from methanol/water provided the title compound (2.79 g; 55% yield) as yellow-white crystals, m.p. 230°-231° C. (dec.).
