反応手順

To 7 parts of magnesium is added dropwise a solution of 50 parts of 1-bromo-2-methylbenzene in 140 parts of 1,1'-oxybisethane so that the mixture is refluxing. The whole is stirred for 15 minutes at reflux. The Grignard-complex is cooled to 10° C. and there is added dropwise a solution of 30 parts of 1-(phenylmethyl)-4-piperidinecarbonitrile in 70 parts of 1,1'-oxybisethane. Upon completion, stirring is continued for 4 hours at room temperature. The reaction mixture is decomposed with a solution of 40 parts of ammonium chloride in 400 parts of water. The organic phase is separated, dried, filtered and evaporated, yielding 31 parts of (2-methylphenyl) [1-(phenylmethyl)-4-piperidinyl]methanone as an oily residue.
