Reaction Conditions

Reaction Steps

95 ml of triethylamine (0.674 mol) were added to a solution of 83 g of 2-hydroxy-4-methylaniline (0.674 mol) in 2.5 liters of tetrahydrofuran, with stirring and under an inert atmosphere, followed, after 30 minutes, by dropwise addition of a solution of 54 ml of chloroacetyl chloride (0.678 mol) in 60 ml of tetrahydrofuran, while maintaining the temperature at 25-27° C. The reaction medium was stirred at room temperature for 4 hours, filtered through a sinter funnel and the inorganic salts were rinsed with 500 ml of tetrahydrofuran. The combined organic phases were poured into 3 liters of ice-cold water with stirring. The precipitate formed was spin-filtered, washed with twice 600 ml of water and once with pentane, and dried under vacuum to constant weight, to give 99 g of 2-chloro-N-(2-hydroxy-4-methylphenyl)acetamide in the form of a beige-coloured powder, in a yield of 74%.
