Methyl iodide → HCID 70873347, compound

Participants

Reaction Steps

60% sodium hydride (0.225 g, 5.2 mmol) was added to an N,N-dimethylformamide solution (20 ml) of 1-(4-benzyloxyphenyl)-4-(4-trifluoromethylphenyl)piperidin-4-ol (2 g, 4.7 mmol) and iodomethane (0.585 ml, 9.4 mmol) under an argon atmosphere while ice cooling, followed by stirring at the same temperature. After 2 hours, the mixture was poured into ice water, and the precipitate was collected by filtration. The resulting solid was dissolved in ethyl acetate/dichloromethane and dried over sodium sulfate. After removing the desiccant by filtration, the solvent was distilled off. The residue was purified by silica gel column chromatography (dichloromethane:ethyl acetate=100:0→95:5) to afford the title compound as a white powder (1.64 g, 79%).
