Reaction Steps
A mixture of 2-chloro-4-(1-pyrrolidinylmethyl)-benzaldehyde (prepared according to the teachings in WO2008/148868) (10.0 g, 44.70 mmol) and tetrabromomethane (22.2 g, 67.05 mmol) in DCM (300 ml) was stirred at 0° C. A solution of triphenylphosphine (35.2 g, 134.10 mmol) in DCM (500 ml) was added. The mixture was stiffed for 30 min at 0° C. The mixture was concentrated in vacuo. The residue was taken up into CHCl3, and the precipitate was filtered off. The filtrate was concentrated in vacuo. The residue (crude 1-[[3-chloro-4-(2,2-dibromoethenyl)phenyl]methyl]-pyrrolidine) was used as such in the next reaction step.
