Reaction Steps

As in Example 113, (E)-3-(1-butyl-5-methoxy-2-naphthalenyl)-2-propenoic acid (1.4 g) was reacted with 4-nitrophenol (0.76 g) in dichloromethane (25 mL) in the presence of 1,3-dicyclohexylcarbodiimide (1.02 g) to give 1.51 g of (E)-3-(1-butyl-5-methoxy-2-naphthalenyl)-2-propenoic acid 4-nitrophenyl ester. Crystallization of a portion from diethyl ether afforded the analytical sample, mp 115°-116° C. Anal. Calcd for C24H23NO5 : C, 71.10; H, 5.72; N, 3.45 Found: C, 71.25; H, 5.75; N, 3.39
