実験手順

To a suspension of 2-methyl-6-acetamidobenzyl alcohol (30 g) and triethylamine (46.54 ml) in methylene chloride (300 ml) was added dropwise mesyl chloride (14.25 ml) below 8° C. The mixture was stirred under ice cooling for 30 minutes and then at room temperature for 20 minutes. The reaction mixture was washed with 1N-hydrochloric acid solution, water and saturated sodium bicarbonate aqueous solution, dried over magnesium sulfate and evaporated in vacuo. The residue was suspended in n-hexane and the precipitates were collected by filtration and dried to give 2-methyl-6-acetamidobenzyl chloride (19.28 g).
