As in Example 134, a solution of (E)-5,5-bis(4-fluorophenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (1.63 g) and alpha,alpha-dimethyl-3-pyridinebutanamine (0.9 mL) in tetrahydrofuran (20 mL) was stirred at reflux for 24 hours. The crude product, isolated in the usual manner, was crystallized from ethyl acetate to yield 1.6 g of (E)-5,5-bis(4-fluorophenyl)-N-[1,1-dimethyl-4-(3-pyridinyl)butyl]-2,4-pentadienamide, mp 163.5°-164.5° C.
