Reaction Steps
To a stirred mixture of 65.2 g (295 mmol) of 3,5-di-tert-butyl-4-hydroxyaniline and 23.3 g (295 mmol) of pyridine in 700 ml of ether cooled to 3° C. there was slowly added 41.6 g (295 mmol) of 4-chlorobutyryl chloride. Fifteen hours later 700 ml of ethyl acetate was added and the mixture was washed successively with 500 ml of water, 500 ml of dilute sodium bicarbonate solution and again with 500 ml of water. The organic phase was dried over anhydrous magnesium sulfate and concentrated to a solid (85.3 g). This solid was triturated in hexane and filtered to yield 75.2 g of N-(3,5-di-tert-butyl-4-hydroxyphenyl)-4-chlorobutyramide.
