Versuchsvorschrift
A mixture of 12 parts of ethyl 4-(3-methylbenzoyl)-1-piperidinecarboxylate and 225 parts of a hydrobromic acid solution 48% in water is stirred and refluxed for 3 hours. The reaction mixture is evaporated and the residue is crystallized from 2-propanol, yielding 7.5 parts of (3-methylphenyl) (4-piperidinyl)methanone hydrobromide.
