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

Participants

Reaction Steps

As in Example 134, a solution of (E)-5,5-bis(3-nitrophenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (0.950 g) and 3-pyridinebutanamine (0.34 g) in tetrahydrofuran (10 mL) was stirred at room temperature for 1 hour. The crude amide that had been isolated in the usual way, was crystallized from ethyl acetate-hexane to yield 0.82 g of (E)-5,5-bis(3- nitrophenyl)-N-[4-(3-pyridinyl)butyl)-2,4-pentadienamide mp 158°-159° C.
