Reaction Steps
To a solution of 3-(4-hydroxy-5-oxo-3-phenyl-2,5-dihydro-2-furyl)propionic acid (80 g) in ethanol (3.2 () was added dropwise conc. sulfuric acid (160 ml) over a period of 0.5 hour and the mixture was stirred for 2.5 hours at ambient temperature. Evaporation of ethanol gave a residue which was poured into ice-cold water (2.4 () and extracted with chloroform. The extract was washed with water and brine successively and evaporated to dryness to give ethyl 3-(4-hydroxy-5-oxo-3-phenyl2,5-dihydro-2-furyl)propionate which was recrystallized from diisopropyl ether (87.05 g).
