Reaction Steps

A mixture of 5 grams (29 mmol) of dimethylphenylphosphonite with 7.5 grams (29 mmol) of 3,5-di-tert-butyl-4-hydroxybenzyl chloride (CAS REG #955-01-1) is heated at 110° C. for 1 hour and cooled to obtain a white solid. The resultant solid is crystallized from 100 mL of hexane to give 9 grams (83% yield) of (3,5-di-tert-butyl-4-hydroxy-benzyl)-phenyl-phosphinic acid methyl ester as a white solid mp 112-114° C.
