실험 절차

4.71 parts of cis-4-amino-5-chloro-2-methoxy-N-(3-methoxy-4-piperidinyl)benzamide, 3.66 parts of sodium carbonate, 0.1 parts of potassium iodide and 120 parts of 4-methyl-2-pentanone was stirred and refluxed for 15 minutes using a water separator. 6 parts of α-(2-bromopropyl)-N,N-dimethyl-α-phenylbenzeneacetamide were added and stirring was continued for 2.5 hours at reflux. Water was added. The organic layer was separated, washed with a sodium chloride solution, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol, saturated with ammonia, (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was suspended in 2,2'-oxybispropane. The product was filtered off and crystallized from acetonitrile, yielding 2.83 parts (31.8%) of cis-4-[(4-amino-5-chloro-2-methoxybenzoyl)amino]-3-methoxy-N,N,γ-trimethyl-α,α-diphenyl-1-piperidinebutanamide; mp. 198.3° C. (compound 54).
