Hydrochloric Acid → Benzyl 4-(4'-decyloxybenzoyloxy)benzoate

참여 물질

반응 단계

In 10 ml of pyridine was dissolved 2.3 g of benzyl p-hydroxybenzoate, a solution of 3 g of p-decyloxybenzoic acid chloride in 15 ml of pyridine was added to the above solution, and a reaction was carried out at room temperature overnight. The reaction liquid was put in ice-cooled dilute hydrochloric acid and the formed precipitate was recovered by filtration, dried and purified by the silica gel chromatography to obtain 4 g of benzyl 4-(4'-decyloxybenzoyloxy)benzoate. This ester was dissolved in 20 ml of ethyl acetate and 0.4 g of Pd/C was added. Catalytic reduction was carried out under a hydrogen pressure of 2 kg/cm2 overnight. The catalyst was removed by filtration, and ethyl acetate was evaporated from the reaction liquid to obtain 3.2 g of 4-(4'-decyloxybenzoyloxy)benzoic acid.
