Sodium hydride → HCID 86617144, compound

Participants

Reaction Steps

Sodium hydride (0.10 g) was added to a DMF solution (12 ml) of 4-methyl-5-pentafluoroethyl-4H-[1,2,4]triazol-3-thiol (0.70 g), and the mixture was stirred at room temperature until the generation of hydrogen gas stopped. Continuously, 5-fluoro-2-nitrotoluene (0.47 g) was added thereto and the mixture was further stirred at room temperature for 1 hour. After cooling to room temperature, the reaction mixture was poured into ice water and extracted with ethyl acetate. The organic layer was washed with saturated aqueous solution of sodium chloride and then dried with anhydrous sodium sulfate. After distilling off the solvent, the obtained residue was purified by silica gel column chromatography (mixed solvent of n-hexane and ethyl acetate) to obtain the aimed 4-methyl-3-(3-methyl-4-nitrophenyl sulfanyl)-5-pentafluoroethyl-4H-(1,2,4)-triazole (0.55 g).
