Reaction Steps

As in Example 113, (E)-3-(1-butyl-7-methoxy-2-naphthalenyl)-2-propenoic acid (1.35 g) was reacted with 4-nitrophenol (0.73 g) in dichloromethane (25 mL) in the presence of 1,3-dicyclohexylcarbodiimide (0.99 g) to give 1.6 g of (E)-3-(1-butyl-7-methoxy-2-naphthalenyl)-2-propenoic acid 4-nitrophenyl ester. Crystallization of a portion from diethyl ether furnished the analytical sample, mp 114°-115° C. Anal. Calcd for C24H23NO5 : C, 71.10; H, 5.72; N, 3.45 Found: C, 70.85; H, 5.56; N, 3.24
