Procedure

To a suspension of 2.65 g of 1,3-dimethyl-4-(2-nitro-5-methylbenzoyl)-5-pyrazolone in 20 ml of dry benzene was added 1.62 g of sulfuryl chloride and the mixture was stirred at room temperature for 4 hours. After completion of the reaction, the reaction mixture was treated in the same manner as in the Example 1 to give 2.0 g of the desired product melting at 110° - 111° C. (Yield 64.72%)
