Procedure
A solution of 2.56 g of phenyl chloroformate in 20 ml of toluene was added to a cold solution of 2.47 g of 4-chloro-2,6-dimethylaniline and 2.4 ml of N,N-dimethylaniline in 80 ml of toluene. The resulting mixture was stirred at room temperature for 11/2 hours and then diluted with water The organic layer was washed with 3N hydrochloric acid, brine, dried, and evaporated. The residual solid was crystallized from ethylacetate:hexane to yield phenyl-N-(4-chloro-2,6-dimethylphenyl)carbamate, mp 158°-160° C.
