Participants

Reaction Steps

As in Example 115, (E,E)-5-(4-fluorophenyl)-2,4-decadienoic acid (4.78 g) and 4-nitrophenol (3.14 g) in 20 mL of dichloromethane was treated with 1,3- dicyclohexylcarbodiimide (3.8 g) and the mixture was stirred at room temperature for 3 days. After the usual work up. crystallization of the crude ester from 2-propanol-hexane gave 4.86 g of (E,E)-5-(4-fluorophenyl)-2,4-decadienoic acid 4-nitrophenyl ester, mp 71°-72,5° C.
