Participants

Reaction Steps

3-Anilinoacrolein-aniline (27.7 g, 0.125 mol) and n-octyl cyanoacetate (26.3 ml, 0.125 mol) are heated in 70 ml of acetic anhydride at 115° C. for 2 hours while bubbling with nitrogen. After cooling, 80 ml of methanol are added and precipitation is allowed to take place. The solid obtained is filtered off and rinsed with methanol. Drying is carried out. 36.4 g of a yellow powder (yield: 79%) of butyl (2E,4E)-5-[acetyl(phenyl)amino]-2-cyanopenta-2,4-dienoate are recovered, which powder is used as is in the following stage.
