Reaction Steps

As in Example 115, a solution of (E)-5,5-bis [(1,1'-biphenyl)-4-yl]-2,4-pentadienoic acid (0.673 g) and 4-nitrophenol (0.256 g) in dichloromethane (7 mL) was treated with 1,3-dicyclohexylcarbodiimide (0.345 g). The mixture was stirred at room temperature for 1.5 hours. The usual work up furnished 0.88 g of (E)-5,5-bis[(1,1'-biphenyl)-4-yl]-2,4-pentadienoic acid 4-nitrophenyl ester.
