Versuchsvorschrift

N-phenyl glycine (0.15 mole) was added with stirring over a 15 minute period to n-butyl isocyanate (0.15 mole). After the addition was complete the reaction mixture was refluxed for about 6 hours and then allowed to stand at room temperature until it solidified. The solidified mass was crystallized from ethanol and produced 0.065 moles of the above-described product having a melting point of 74° l C.
