Pyridine, 3-(4-aminobutyl)- → (E)-5,5-bis(4-methoxyphenyl)-N-[4-(3-pyridinyl) butyl]-2,4-pentadienamide

Participants

Reaction Steps

As in Example 134, a solution of (E)-5,5-bis(4-methoxyphenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (4.3 g) and 3-pyridinebutanamine (1.51 g) in tetrahydrofuran (20 mL) was stirred for 1.5 hours at room temperature and was worked up in the usual fashion. The crude product was crystallized from ethyl acetate-hexane to provide 3.6 g of (E)-5,5-bis(4-methoxyphenyl)-N-[4-(3-pyridinyl) butyl]-2,4-pentadienamide mp 76°-77° C.
