Dimethylformamide → HCID 15869809, compound

Participants

Reaction Steps

To a mixture of 0.34 g (0.9 mmol) of 2-[2-(4-chloro-2-methylphenoxymethyl)-α-hydroxybenzyl]-1-methylimidazole, 3 ml of N,N-dimethylformamide and 0.13 ml (1.8 mmol) of ethyl bromide was added 0.05 g (1.3 mmol) of 60% sodium hydride under ice-cooling and stirred at the same temperature for 3 hours. After completion of the reaction, 100 ml of ether was added and washed twice with 80 ml of brine. The ether layer was dried over anhydrous magnesium and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (ethyl acetate/n-hexane) to give 2-[2-(4-chloro-2-methylphenoxymethyl)-α-ethoxybenzyl]-1-methylimidazole (0.30 g, 89.9%) as colorless oil.
