Procedure
A solution of 2.0 g of 2-chlorobenzoyl isocyanate in 5 ml of dry toluene was added to a stirred suspension of 3.0 g of N-[4-(trifluoromethoxy)phenyl]-2-methyl-benzenesulphenamide in 40 ml of dry light petroleum at room temperature. After a few minutes, the reaction mixture became clear and subsequently the product came out of solution as an oil which eventually crystallized. After 24 hours the reaction mixture was cooled to -5° C. and filtered, and the pale purple product was washed with cold light petroluem. Recrystallization from ether/light petroleum gave 4, as colorless crystals, m.p.: 79°-80° C.
