---|---|---|
91% | With dimethyl amine; In ethanol; isopropyl alcohol; | a) 200 kg of 2-methoxyethyl acetoacetate and 185.1 kg of 3-nitrobenzaldehyde are suspended in 800 l of isopropanol. Then 5.65 kg of p-anisic acid and 5.05 kg of 33percent dimethylamine in ethanol are added, heating for about 30' at about 35° C. to obtain a solution. The reaction mixture is left to cool at 20/25° C. and then it is cooled for about 12 hours with running water and for a further 24 hours at about 0° C. with brine, then is centrifuged, washing with isopropanol. After drying, 327 kg of 2-methoxyethyl 2-(3-nitrobenzylidene) acetoacetate are obtained, in an about 91percent yield. |
