Sodium hydride → 4-(4-fluorophenyl)-1-[1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl]butane-1,3-dione

Participants

Reaction Steps

To a solution of 1-[1-(4-methoxybenzyl)-1H-1,2,3-triazol-4-yl]ethanone (1.0 g, 4.30 mmol) in anhydrous THF (25 mL) was added NaH (0.38 g, 9.5 mmol) at 0° C. The mixture was stirred at RT for 1 hour, and (4-fluoro-phenyl)-acetic acid methyl ester (1.67 g, 10.0 mmol) was added at 0° C. and the mixture was refluxed overnight. The reaction mixture was evaporated and the residue was purified via column chromatography (silica gel, EtOAc/Petroleum ether 1:5) to yield the title compound (0.6 g, 38.0%) as a colorless oil.
