Procedure

As in Example 112, (E)-3-(1-butyl-7-methoxy-2-naphthalenyl)-2-propenoic acid methyl ester (1.55 g) in methanol (20 mL) was treated with 2N sodium hydroxide solution (4 mL) at reflux for 2 hours and the normal isolation procedure afforded 1.45 g of (E)-3-(1-butyl-7-methoxy-2-naphthalenyl)-2-propenoic acid. Crystallization of a sample from diethyl ether gave the analytical specimen. Anal. Calcd for C18H20O3 : C, 76.03; H, 7.09 Found: C, 75.66; H, 7.13
