Reaction Steps

To a solution of 25 milliliters of diethylamine in 50 milliliters of dry benzene was added a solution of 2.0 grams of 3,5-di-t-butyl-4-hydroxybenzoyl chloride in benzene. The resulting mixture was refluxed for 1 hour, cooled, and poured into 100 milliliters of cold water. The excess amine was neutralized with dilute hydrochloric acid; the benzene layer was removed, washed with water, dried, and evaporated, leaving an oil. Addition of a small amount of petroleum ether gave crystals, which were filtered, and recrystallized from heptane, yielding 1.3 grams of N,N-diethyl-3,5-di-t-butyl-4-hydroxybenzamide; melting point 136°-137.5°C.
