Procedure

A mixture of ethyl 5-methyl-2,4-dinitrobenzoate (39 g, 0.15 mol) and DMA (32 g, 0.27 mol) in DMF (200 mL) was heated at 100° C. for 5 h. The mixture was poured into ice water and the precipitated solid was filtered and washed with water to afford (E)-ethyl 5-(2-(dimethylamino)vinyl)-2,4-dinitrobenzoate (15 g, 28%).
