Procedure

Five grams of 4-(4'-hydroxyphenyl)benzoic acid, 5 g of (s)-2-methylbutylalcohol and 11 g of p-toluenesulfonic acid were dissolved with 50 ml of benzene. Occurred water in the mixture was removed by azotropic dehydration with refluxing for eight hours. After adding 50 ml of water to the residue, the organic phase was concentrated to obtain 4-(4'-hydroxyphenyl)benzoic acid-2-methylbutyl ester (BJ).
