Reaction Steps

To a stirred mixture of 3.6 g (16 mmol) of 3,5-di-tert-butyl-4-hydroxyaniline and 1.3 g (16 mmol) of pyridine in 50 ml of ether cooled to 0° C. there was slowly added 2.5 g (16 mmol) of 5-chlorovalerylchloride. The reaction mixture was allowed to warm to 25° C. and stirred for 15 hours following which the mixture was diluted with 100 ml of ether, washed with water, dried over anhydrous magnesium sulfate and concentrated to 5.8 g of solid. The solid was triturated in hexane and filtered to yield 5.5 g (16 mmol) of N-(3,5-di-tert-butyl-4-hydroxyphenyl)-5-chlorovaleramide.
