Reaction Conditions

Reaction Steps

A solution of 2-chlorobenzoyl isocyanate (2.7 g) in dry toluene (5.0 ml) was added to a stirred suspension of isopropyl 2-[[[4-(trifluoromethoxy)phenyl]amino]thio]benzoate (3.7 g) in the same solvent (20.0 ml) at room temperature. After 18 hours, a cake of crystals had formed. The reaction mixture was cooled to -5° C. and filtered, washing the crystals with cold toluene followed by light petroleum. After drying at 40° C. under vacuum, the pure product was obtained as colourless crystals (4.8 g). Melting point 143°-144° C.
