Procedure
To a solution of 1-[3-(4-hydroxymethylphenoxy)propyl]piperidine (5.617 g) in dichloromethane (50 mL), cooled at a temperature close to 0° C., is added dropwise thionyl chloride (3 mL). The mixture is stirred for 18 hours at room temperature and concentrated under reduced pressure. The residue is crystallized in diethyl ether to give 1-[3-(4-chloromethylphenoxy)propyl]piperidine as an off white solid used without further purification.
