The crude 6-MPCN product of Example I was dissolved in 135 ml of methanol and 40 ml of a potassium hydroxide solution (4.5 g of KOH in 40 ml of water) and heated to 125° C./70 psi for seven hours. The reaction mixture was then worked up and acidified to yield 6.6 g of 6-methoxy-5-pentafluoroethyl-1-naphthoic acid.
