Reaction Steps

According to the teachings in EP 0235795, a suspension of 3-bromopropyltriphenylphosphonium bromide (Olo-IM4) in ethanol was reacted with 13.5 equivalents of an aqueous dimethylamine solution (50%) to provide dimethylaminopropyltriphenylphosphonium bromide HBr. After this reaction, the solvent was distilled off and the residue was recrystallized (yield: 59%).
