Procedure
From the reaction of 5-methyl-2-(4-aminophenyl)-2,4-dihydro-pyrazol-3-one and methansulfonylchloride (reaction per Example 11, where methanesulfonylchloride is used in respective molecular amounts), N-(4-(4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-phenyl)-N-methylsulfonylmethanesulfonamide is obtained. Subsequent reaction with 2-ethyl aniline yields N-(4-(4-(2-Ethylanilinomethylene)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl)-phenyl)-N-methylsulfonylmethansulfonamide, Mp: 268° C.
