Benzyl 4-Hydroxybenzoate → HCID 13587738, compound

Participants

Reaction Steps

Into a 500 ml four-neck flask equipped with a condenser tube and a thermometer are charged 56 g of benzyl p-hydroxybenzoate, 25 g of triethylamine and 60 ml of toluene. A suspension of 25 g of terephthalic dichloride in 100 ml of toluene is added dropwise with stirring while retaining the mixture at 0°-5° C. over 3 hours. After addition, the mixture is further allowed to react at 0°-5° C. for 1 hour. Thereafter the resulting reaction product is collected by filtration to obtain white crystals. The crystals are washed with 1500 ml of water twice and then with 1000 ml of methanol twice and subsequently, recrystallized from chloroform to give di(p-benzyloxycarbonylphenyl)terephthalate melting at 186°-187° C. as white crystals.
