Reaction Steps

1.28 g (8.4 mmol) of cesium fluoride was weighed into a flask and dried under a reduced pressure at 130° C. for 30 minutes. 50 g (0.42 mol) of phenyl isocyanate and 39.5 g (0.42 mol) of phenol were added thereto with stirring at 105° C. for 10 minutes, followed by the removal of an unreacted raw material at a reduced pressure. Thus, 88.3 g of phenyl N-phenylcarbamate having a melting point of 123° to 124° C. was obtained at a yield of 93.1%.
