반응 단계
4,4'-Methylenebis(cyclohexylamine) (56.5 g, 0.27 mole) was dissolved in hot isopropanol (500 ml) and glycolic acid (40.9 g, 0.54 mole) added portion-wise with stirring. Upon cooling, a white gummy solid separated which was isolated by decantation and redissolved in a small volume of ethanol. Crystallization produced a white crystalline, deliquescent solid; m.p. 96°-102° C. Thorough drying under vacuum increased the melting point (m.p. 149°-151° C.) and reduced the deliquescence.
