Reaction Steps

A mixture of 50 g (0.266 mole) 3-hydroxy-2-naphthoic acid, 27.3 g (0.29 mole) phenol, and 21.4 g (0.14 mole) phosphorus oxychloride was stirred and heated at 100° C. for 3.5 hrs. Then 200 ml alcohol was added, and the mixture was heated one hour longer and cooled. The yellow product was collected and recrystallized from benzene to give 26.4 g (38%) of phenyl-3-hydroxy-2-naphthoate, m.p. 126°-130° C.
