실험 절차

A mixture of N-phenyl glycine (0.1 mole), cyclohexyl isocyanate (0.12 mole) and toluene (30 ml) was refluxed for about 6 hours and then cooled. The crude product was recrystallized from ethanol to produce a 60% yield of the above-identified product having a melting point of approximately 196° C.
