Participants

Reaction Steps

A solution of 9.8 g of 2-(3,5-di-tert-butyl-4-hydroxyphenylthio) ethanol and 3.1 g of pyridine in 40 ml of toluene was added at 15°-20° C. over five minutes to a solution of 9.4 g of 3,5-di-tert-butyl-4-hydroxybenzoyl chloride in 50 ml of toluene. The reaction mixture was stirred at room temperature for 15 hours and then the resultant precipitate of triethylamine hydrochloride was removed by filtration. The solvent was removed in vacuo and the residue was recrystalized from n-heptane to give 15 g (84%) of a white solid, mp 136°-139° C.
