Procedure

In a similar way to Example 37, reaction of 2.5 g of 2-(3-amino-4-chlorophenyl)-3-chloro-5-trifluoromethylpyridine and 1.9 g of 4-chlorobenzenesulfonyl chloride, and purification of the crude product by recrystallization from ether, resulted in 1.2 g of colorless crystals. Yield: 31%; melting point: 156°-157° C.
