Versuchsvorschrift

A mixture of 1-benzyl-4-piperidinecarbonylchloride hydrochloride (25.0 g, 91 mmol), 10,11-dihydro-5H-dibenzo[b,f]azepine (17.6 g, 90 mmol), N,N-dimethylaniline (25 ml) and toluene (150 ml) was heated at reflux temperature under stirring for 14 h. The mixture was decanted and to the remaining solid 10% ammonia (100 ml) and chloroform (150 ml) were added. The phases were separated and the combined toluene and chloroform phases were dried (K2CO3) and evaporated in vacuo. The residue was purified by chromatography on silica gel (300 g) using benzene and ethyl acetate as eluents. The crude base was crystallised from cyclohexane, yielding 13.0 g (36%) of 4-((10,11-dihydro-5H-dibenz[b,f]azepin-5-yl)carbonyl)-1-benzylpiperidine.
