Reaction Steps
4-Methoxyphenol was added to a solution of NaOC2H5 made by dissolving 2.3 g of Na in 50 ml ethanol. After 5 minutes, gamma-butyrolactone was added and the mixture heated at reflux overnight. Ethanol was distilled off and the residue heated at 155° C. overnight, then cooled, diluted with water and acidified to pH 3 with dilute hydrochloric acid. The product was collected by filtration, 19.5 g, m.p. 103°-104° C.
