Procedure
To a stirred solution of 1.08 g of 4-trifluoromethylbenzoylisocyanate in 5 ml of dry diethylether is added a solution of 0.64 g of 4-chloroaniline in 50 ml of acetonitrile. A precipitate is immediately formed. The precipitate is sucked off and washed with acetonitrile. The title compound is obtained a yield of 1.1 g; melting point 260° C.
