Procedure
1-(3-Methyl-4-nitrophenyl)-ethyl methanesulfonate (2.59 g), 3-trifluoromethyl-1H-pyrazole (1.09 g), potassium carbonate (1.66 g) and 18-crown-6 (0.26 g) were refluxed in acetonitrile (100 ml) for 6 hours. After finishing the reaction, water (100 ml) was added to the mixture and extracted with ethyl acetate. The organic layer was washed with saturated aqueous solution of sodium bicarbonate and then dried with anhydrous sodium sulfate. After distilling off the solvent, the obtained residue was purified by silica gel column chromatography to obtain 1-[1-(3-methyl-4-nitrophenyl)-ethyl]-3-trifluoromethyl-1H-pyrazole (1.60 g).
