Reaction Steps

100 mL of diphenyl ether was heated to reflux followed by addition of 5.00 g (13.6 mmol) diethyl 2-((2-bromo-4-cyanophenylamino)methylene)malonate in portions in 30 minutes. The resulting brown solution was reflux for another hour and then cooled down to room temperature. The precipitate was collected and washed with hexanes (15 mL×3) to give 5.69 g of a light brown solid as the desired product. MS ESI (m/z) 321 (M+1)+.
