Nitromethane → 4-Bromo-2-methoxy-1-(2-nitrovinyl)benzene

Participants

Reaction Steps

A suspension of 4-bromo-2-methoxybenzaldehyde (1.55 g; 7.2 mmol), methylamine hydrochloride (0.31 g; 50.4 mmol) and sodium acetate (0.38 g; 4.6 mmol) in 3 mL of nitromethane was stirred at ambient temperature. After stirring for 14.5 hours the mixture was diluted with 20 mL water and 40 mL dichloromethane, and the mixture was transferred to a separatory funnel. After shaking, the organic layer was dried over sodium sulfate and evaporated to give 1.74 g of 4-bromo-2-methoxy-1-(2-nitrovinyl)benzene as a light yellow solid. MS (apci, neg) m/z=257.
