Thionyl Chloride → HCID 15087728, compound

Participants

Reaction Steps

160 Parts of thionyl chloride were added dropwise to 10 parts of (E)-5-(4-fluorophenyl)-5-(3-pyridinyl)-4-penten-1-ol while stirring (exothermic reaction, the temperature rose to 45° C.). Upon complete addition, stirring was continued for 2 hours at room temperature. The reaction mixture was evaporated. The residue was taken up in methylbenzene and the solvent was evaporated again. The residue was solidified in 2,2'-oxybixpropane. The product was filtered off and dried, yielding 11.5 parts (94.4%) of (E)-3-[5-chloro-1-(4-fluorophenyl)-1-pentenyl]pyridine hdyrochloride (int. 60).
