Reaction Steps
A solution of 6.22 g (0.02 mol) of propyl 2-(4-bromobenzylidene)acetoacetate and 3.14 g (0.02 mol) of propyl 3-methylamino-crotonate in 25 ml of 2-butanol is stirred under reflux for 10 hours. The mixture is then concentrated in vacuo, and the precipitate formed in the cold is filtered off with suction. After recrystallization from propanol, 5.32 g (59.1% of theory) of melting point 97°-99° C. are obtained.
