실험 절차

[1,1′-Biphenyl]-2-carboxylic acid (0.25 mol) was dissolved in DCM (500 ml) and DMF (0.5 ml). Thionyl chloride (0.51 mol) was added dropwise. The mixture was stirred and refluxed for 1 hour under nitrogen flow. The solvent was evaporated. DCM (500 ml) was added twice. The solvent was evaporated twice. The residue was dissolved in DCM (200 ml) and then added dropwise at 0° C. to a mixture of 4-[1-(phenylmethyl)-4-piperidinyl]-benzenamine (0.25 mol) and N-(1-methylethyl)-2-propanamine (0.75 mol) in DCM (800 ml). The mixture was brought to room temperature and then stirred at room temperature overnight under nitrogen flow. The mixture was washed three times with water (800 ml). The organic layer was separated, dried, filtered and the solvent was evaporated, yielding 125 g of N-[4-[1-(phenylmethyl)-4-piperidinyl]phenyl]-[1,1′-biphenyl]-2-carboxamide (intermediate 18).
