Procedure

As in Example 115, 5-pentyl-2,4-decadienoic acid (4.0 g) and 4-nitrophenol (2.8 g) in 30 mL of dichloromethane was treated with 1,3-dicyclohexylcarbodiimide (3.48 g) and the mixture was stirred at room temperature for 18 hours. After the usual work up, the crude ester was Purified by HPLC (ether-hexane; 1:24) to furnish 2,45 g of 5-pentyl-2,4-decadienoic acid 4-nitrophenyl ester as an oil.
