Pyridine → 1-{4-[4-(5-Fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-trifluoromethylpentyl]-2,6-dimethylpiperazin-1-yl}ethanone

Participants

Reaction Steps

To a solution of 2-(3,5-dimethylpiperazin-1-ylmethyl)-1,1,1-trifluoro-4-(5-fluoro-2-methoxyphenyl)-4-methylpentan-2-ol (18 mg) in methylene chloride (1 mL) was added pyridine (55.8 μL) followed by acetic anhydride (43.4 μL). The resulting mixture was stirred overnight, quenched with saturated aqueous sodium bicarbonate solution and extracted twice with methylene chloride. The combined organic phases were dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by column chromatography with silica gel (eluted with 50% ethyl acetate-hexanes) to give the title compound as a clear oil (20 mg).
