Reaction Conditions

Reaction Steps

A solution of 2-bromoanisole (50.0 g, 0.267 mol) in ether is added portionwise to a mixture of magnesium (7.10 g, 0.293 mol) in ether. After the addition is complete, the reaction mixture is heated at reflux for one hour, diluted with ether, cooled to 0° C., treated with a solution of 2-chloro-5-nitrobenzaldehyde (39.0 g, 0.210 mol) in tetrahydrofuran, warmed to room temperature, and diluted with an ice-water mixture. After acidifying the aqueous mixture with hydrochloric acid (pH 2--pH 3), the organic phase is separated and the aqueous phase is extracted with ether. The organic extracts are combined, washed sequentially with 10% sodium hydrogen carbonate solution and brine, dried over anhydrous sodium sulfate, and concentrated in vacuo to give the title product as a brown gum.
