Reaction Steps
The methyl 3-methoxy-2-naphthoate was diluted with excess 5 percent sodium hydroxide solution and the mixture was heated at its reflux temperature until the solution was clear. The solution was acidified with hydrochloric acid to provide a precipitate which was separated by filtration. Recrystallization from benzene provided the known intermediate 3-methoxy-2-naphthoic acid, m.p. 130°-132° C.
