Versuchsvorschrift

As in Example 134, a solution of (E)-5,5-bis(4-fluorophenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (15 g) and 3-pyridinebutanamine (5.53 g) in tetrahydrofuran (60 mL) was stirred for 1.5 hours at room temperature and was worked up in the usual manner. The crude amide was crystallized from ethyl acetate-hexane (2x) to give 14.45 g of (E)-5,5-bis(4-fluorophenyl)-N-[4-(3-pyridinyl) butyl]-2,4-pentadienamide mp 155°-156° C.

Aufarbeitung

  1. customThe crude amide was crystallized from ethyl acetate-hexane (2x)
