실험 절차

As in Example 134, a solution of (Z)-5,5-bis(3-methoxyphenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (1.2 g) and 3-pyridinebutanamine (0.42 g) in tetrahydrofuran (7 mL) was stirred at room temperature for 1 hour. The crude amide that had been isolated in the usual way, was contaminated with a minor amount of the (E)-isomer. The mixture was separated by HPLC (ethyl acetate) and the desired product was crystallized from ether (2×) to yield 0.48 g of (Z)-5,5-bis(3-methoxyphenyl)-N-[4-(3-pyridinyl)-butyl]-2,4-pentadienamide mp 69°-73° C.
