Reaction Steps

A mixture of 14.4 parts of N-(3-bromopropyl)-2-nitrobenzamide, 12.2 parts of (4-fluorophenyl) (4-piperidinyl)methanone hydrochloride, 16 parts of sodium carbonate and 200 parts of 4-methyl-2-pentanone is stirred and refluxed for 3 hours using a water-separator. The reaction mixture is cooled, water is added and the layers are separated. The organic phase is dried, filtered and evaporated. The oily residue is purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (90:10 by volume) as eluent. The pure fractions are collected and the eluent is evaporated, yielding 18 parts (87%) of N-[3-[4-(4-fluorobenzoyl)-1-piperidinyl]propyl]-2-nitrobenzamide as an oily residue.
