To 2-bromobenzaldehyde (27 g; 0.146 mmol.) in dry tetrahydrofuran cooled to -78° C. in a dry ice/isopropyl alcohol bath was added 175 ml of a 1.0M solution of vinyl Grignard reagent in tetrahydrofuran dropwise and the reaction allowed to slowly warm overnight to room temperature. The reaction mixture was quenched with saturated NH4Cl and the tetrahydrofuran was concentrated off. The reaction mixture was poured into water and extracted twice with diethylether, washed with water and then brine and dried over K2CO3 to afford the subtitle compound.
