実験手順
As in Example 134, a solution of (E)-5,5-bis(3-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 for 29 hours at reflux and was then worked up in the usual manner. The crude amide was crystallized from ethyl acetate-hexane to furnish 1.6 g of (E)-5,5-bis(3-fluorophenyl)-N-[l,1-dimethyl-4-(3-pyridinyl)butyl]-2,4-pentadienamide mp 135°-136° C.
