Procedure
As before in Example 134, a solution of (E)-5,5-bis(4-methoxyphenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (1.94 g) and alpha-[3-(3-pyridinyl)propyl]-3-pyridinebutanamine (1.21 g) in tetrahydrofuran (25 mL) was stirred for 20 hours at 50° C. and then was worked up in the normal manner. The crude was purified by HPLC (ethyl acetate-triethylamine; 19:1) and was then lyophilized from benzene to give 1.95 g of (E)-5,5-bis-(4-methoxyphenyl)-N-[1-[3-(3-pyridinyl)propyl]-4-(3-pyridinyl)-butyl]-2,4-pentadienamide as a glass.
