Procedure
13.7 g (55 mmol) of 2-(2-nitrobenzylidene)-acetoacetic acid methyl ester and 16.6 g (55 mmol) of 3-aminocrotonic acid-(4-phthalimido-butyl)ester are boiled in 150 ml of ethanol for 18 hours. The orange yellow oil (28.7 g-98%) obtained after removal of the solvent by evaporation under vacuum is used for further reactions without further purification.
