Reaction Steps

Under a nitrogen atmosphere, a mixture of 3.62 g of 1-(4-bromo-2-nitrophenyl)ethanone and 5.3 g of (dimethoxymethyl)dimethylamine was stirred at 90° C. for 4 hours. The reaction mixture was cooled to room temperature and the precipitated solid was collected by filtration. The obtained solid was washed with diisopropyl ether and dried under reduced pressure to obtain 3.93 g of (2E)-1-(4-bromo-2-nitrophenyl)-3-(dimethylamino)prop-2-en-1-one.
