Versuchsvorschrift
Aqueous hydrobromic acid (48% w/w) was added dropwise, with stirring, to a solution of 1-(4-hydroxybenzyl)-1,2,3,6-tetrahydropyridine (4.0 g.) in acetone (50 ml.) until no further precipitate was obtained. The solid was collected by filtration and recrystallised from ethanol to give 1-(4-hydroxybenzyl)-1,2,3,6-tetrahydropyridine hydrobromide (Example 18) (2.9 g.), m.p. 187°-190° C.
