Mode opératoire

7.25 g of ethyl 2-(4-hydroxyphenyl)-2-oxoacetate was dissolved in 15 ml of pyridine, followed by adding 4 ml of acetic anhydride and then stirring at room temperature for 1 hour. The resulting reaction solution was poured into water, and extracted with diethyl ether. The resulting organic layer was washed with water, and then concentrated to dryness. Thereafter, the residue was dissolved in benzene, and then concentrated to obtain 8.3 g of the title compound in an oily form.
