Reaction Steps

To a stirred solution of (2-dimethylaminoethyl)triphenylphosphonium bromide (1.12 g, 2.7 mmol) in tetrahydrofuran (10 ml) was added 2.5 M n-BuLi in hexanes (1.08 ml, 2.7 mmol) under nitrogen at 0° C. After 30 minutes 4-bromobenzaldehyde (0.5 g, 2.7 mmol) was added slowly and the reaction mixture was stirred at 60° C. overnight. The reaction mixture was acidified with 2M hydrochloric acid and extracted with toluene. The aqueous layer was then made alkaline with 2N sodium hydroxide and extracted twice with ethyl acetate. The organics were combined, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the product as yellow oil. Yield 0.41 g, 63%. LCMS method: 2, RT: 2.62 min; MI: 240-242 [M+1].
