反应详情

A stirred solution of 2,6-dimethyl-3-nitrobenzene-1-methanol (51.3 g, 0.283 mole) and 25 ml of pyridine in 350 ml of toluene was warmed to 70°. During a ten minute period, acetyl chloride (22.2 g, 0.283 mole) was added to the reaction mixture. The reaction mixture was heated at 85° for 21/2 hours, then poured over 300 g of ice, and 100 ml of a 4 N hydrochloric acid solution was added thereto. The organic phase was separated and washed with 100 ml of aqueous 2 N hydrochloric acid, dried over anhydrous magnesium sulfate, and filtered. The solvent was removed from the filtrate under reduced pressure to give (2,6-dimethyl-3-nitrophenyl)methyl acetate (47.5 g) as an oil.
