実験手順

To a stirred solution of 11.2 parts of (4-fluorophenyl)(4-piperidinyl)methanone in 80 parts of 4-methyl-2-pentanone were added 5 parts of N-(2-chloroethyl)-3-pyridinecarboxamide and the whole was stirred and refluxed overnight. The reaction mixture was filtered and the filtrate was evaporated. The residue was purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (95:5 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from a mixture of 4-methyl-2-pentanone and 2,2'-oxybispropane, yielding 1.6 parts (16.5%) of N-[2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl]-3-pyridinecarboxamide; mp. 118.3° C. (intermediate 114).
