Procedure

As in Example 115, (2E,4Z)-5-(3-fluorophenyl)-2,4-decadienoic acid (3.3 g) and 4-nitrophenol (2.1 g) in 20 mL of dichloromethane was treated with 1,3-dicyclohexylcarbodiimide (2.67 g) and the mixture was stirred at room temperature for 3 days. After the usual work up. crystallization of the crude material from hexane gave 3.1 g of (2E,4Z)-5-(3-fluorophenyl)-2,4-decadienoic acid 4-nitrophenyl ester, mp 50°-51° C.

Workup

  1. customcrystallization of the crude material from hexane
