반응 단계

4,4'-Methylenebis(cyclohexylamine) (25 g, 0.12 mole) and glycolic acid (18.2 g, 0.24 mole) were combined in a 250 ml round bottom flask heated in an oil bath. The solids were melted together with mixing and heated to 175° C. whereupon distillation of water occurred. After heating for 3 hours the evolution of water subsided and crystallization commenced. The solid was removed and recrystallized from methanol to yield 34 g (87%) of lustrous white needles; m.p. 208°-212° C.
