Procedure

A solution of (Z)-naphthalene-2-acrylic acid ethyl ester (1.38 g, 6.0 mmole) in a mixture of tetrahydrofuran (10 ml) and water (10 ml) was treated with lithium hydroxide (0.88 g, 37 mmol) and heated to 60° C. for 6 hours. On cooling, the organic phase was separated and the. aqueous phase was acidified and extracted with diethyl ether. The ethereal phase was dried and the solvent removed in vaccuo to give (Z)-3-(2-naphthyl)prop-2-enoic acid as a white solid which was used without further purification, Mp 207-209° C.
