Versuchsvorschrift

Thionyl chloride (1.8 ml) in chloroform (15 ml, alumina dried) was added dropwise to a stirred and cooled solution of 2-hydroxymethyl-3-fluoro-4-morpholinopyridine (1.74 g) in chloroform (20 ml). After 2 hours at room temperature the solution was reduced in volume and ether added. The precipitate was filtered off, washed and dried to give 2-chloromethyl-3-fluoro-4-morpholinopyridine hydrochloride (2.1 g) m.p. 203°-205°.
