Reaction Steps
4-Bromobenzaldehyde (9.25 g) was dissolved in dry dichloromethane (250 ml) at 25° C. under nitrogen. Carbomethoxymethylene triphenylphosphorane (17.4 g) (ex Lancaster) was added and the solution stirred at 25° C. for 18 hours. The solvent was removed under vacuum. The residue was washed with hexane and filtered. Removal of the hexane under vacuum gave ethyl 4-bromocinnamate (12.12 g). NMR 1H; 7.35 (5H,m), 6.38 (1H,d), 4.1(2H,q), 1.35(3H,t).
