实验步骤: Biphenyl acid 10 (40 mg, 0.064 mmol, 1 eq) and HBTU (49 mg, 0.13 mmol, 2 eq) were dissolved in DMF (1 mL) followed by the addition of (S)—N1,N1-dimethyl-3-(thiophen-2-yl)propane-1,2-diamine (23 mg, 0.13 mmol, 2 eq). The reaction mixture was stirred for 2 h, diluted with EtOAc and quenched with a saturated aqueous NaHCO3 solution. The reaction mixture was extracted with EtOAc (3×100 mL) and the combined organics were dried over MgSO4, filtered and concentrated in vacuo to afford an oil. The crude oil was purified by silica gel chromatography (2-5% MeOH/DCM, 0.1% Et3N) to afford 23 mg of biphenyl amide 251. Yield 45%. quenched with a saturated aqueous NaHCO3 solution The reaction mixture was extracted with EtOAc (3×100 mL) the combined organics were dried over MgSO4 filtered concentrated in vacuo to afford an oil The crude oil was purified by silica gel chromatography (2-5% MeOH/DCM, 0.1% Et3N)

实验步骤: 2-Biphenylcarboxylic 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 [1,1′-biphenyl]-2-carboxamide, N-[4-[1-(phenylmethyl)-4-piperidinyl]phenyl]-(intermediate 39). 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) was brought to room temperature 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 the solvent was evaporated
