A suspension of 2,4-dichloro-6-methoxybenzaldehyde (0.51 g; 2.5 mmol), methylamine hydrochloride (0.11 g; 1.6 mmol) and sodium acetate (0.13 g; 1.6 mmol) in 3 mL of nitromethane was stirred at ambient temperature. After stirring for 15.5 hours the mixture was diluted with 20 mL water and 40 mL DCM, and then transferred to a separatory funnel. After shaking, the organic layer was dried over sodium sulfate and evaporated to give 0.57 g of 1,5-dichloro-3-methoxy-2-(2-nitrovinyl)benzene as a light yellow solid. MS (apci, neg) m/z=247
