Procedure
Into a 500 mL round bottom flask was placed a solution of 2-chlorobenzoyl chloride (22.3 g, 127.43 mmol) in toluene (200 mL). To the mixture was added 4-methylbenzenesulfonohydrazide (23.3 g, 125.27 mmol). The resulting solution was allowed to react, with stirring, overnight while the temperature was maintained at 75° C. in a bath of oil. A filtration was performed. The filter cake was dried in an oven under reduced pressure. This resulted in 37.7 g (91%) of 2-chloro-N′-tosylbenzohydrazide as a white solid.
