Procedure

A mixture of 9.0 gm (0.040 mol) of 2,4-difluoro-3,5-dichlorophenyl isocyanate, 6.5 gm (0.042 mol) of 2-chlorobenzamide, and 100 ml of xylene was boiled for five hours under reflux. It was then allowed to cool, and the product which precipitated was removed by suction filtration and dried.
