To 4 g (30 mmoles) of 5-methyl pyrazole 3-carboxylic acid are added 7.1 g (60 mmoles) of thionyl chloride, 150 ml of toluene and several drops of DMF. To the product obtained are then added 7.7 g of 2,6-dimethyl aniline (60 mmoles), 200 ml of toluene and again a few drops of DMF. 2.60 g of the title product are obtained in the form of ochre crystals.
