Procedure
Dimethyl sulfate (1.26 g. 0.01 mole) is added to an anhydrous toluene (50 ml) solution of 3,5-dicyclohexyl-1,4-dimethylpyrazole (1.7 g, 0.0064 mole) with constant stirring at 80° C. The reaction mixture is then heated to reflux and maintained at reflux, with stirring, for 6 hours. The reaction mixture is cooled, ether (75 ml) is added and the mixture stirred for 3 hours. The resulting solid is filtered and dried to give 1,8 g of the desired product, m.p. 176° C to 177° C.
