Procedure
432 g 1-naphthol, 602 g ethyl 2-bromoacetate, 276 g potassium carbonate and 2.160 l. ethanol are refluxed for 18 hours, the precipitate filtered, the solvent evaporated under reduced pressure and the residue recrystallized from petroleum ether. The ester, which melts at 52° C., is obtained with an 80% yield.
