Reaction Steps

As in Example 115, (E,E)-5-(3-methoxyphenyl)-2,4-nonadienoic acid (4.48 g) and 4-nitrophenol (2.97 g) in 25 mL of dichloromethane was treated with 1,3-dicyclohexylcarbodiimide (3 59 g). The mixture was stirred at room temperature for 3 days and after the normal work up. the crude product was crystallized from 2-propanol yield 5.6 g of (E,E)-5-(3-methoxyphenyl)-2,4-nonadienoic acid 4-nitrophenyl ester, mp 81.5°-83° C. Anal. Calcd for C22H23NO5 : C, 69.29; H, 6.08; N, 3.67. Found: C, 68.89; H, 6.08; N, 3.64.
