実験手順

A mixture of 4′-(trifluoromethyl)-[1,1′-biphenyl]-2-carbonyl chloride (0.185 mole) in DCM (1500 ml) and triethylamine (50 ml) was stirred on an ice-bath for 5 minutes. 4-[4-(Phenylmethyl)-1-piperazinyl]-benzenamine (0.37 mole) in DCM (500 ml) was added dropwise. The mixture was stirred for 3 hours. The organic layer was separated, washed with water, dried, filtered and the solvent was evaporated. The residue was triturated in DIPE. The precipitate was filtered off and dried, yielding 99.8 g of N-[4-[4-(phenylmethyl)-1-piperazinyl]phenyl]-4′-(trifluoro-methyl)-[1,1′-biphenyl]-2-carboxamide (intermediate 5, melting point 180° C.).
