실험 절차

DMF (0.5 ml) was added to a solution of 4′-(trifluoromethyl)-[1,1′-biphenyl]-2-carboxylic acid (0.014 mole) in DCM (50 ml) and thionyl chloride (0.028 mole). The mixture was stirred and refluxed for one hour. The solvent was evaporated. DCM (50 ml) was added twice and the solvent was evaporated. The residue was dissolved in DCM (20 ml) and this solution was added to a mixture of intermediate (15) (0.014 mole) and DIPEA (0.028 mole) in DCM (80 ml). The mixture was stirred at room temperature for three hours and washed with water. The organic layer was dried and the solvent was evaporated. The residue was crystallized from 2-propanol. The precipitate was filtered off and dried, yielding 6.2 g of methyl α-phenyl-1-[4-[[[4′-(trifluoromethyl)-[1,1′-biphenyl]-2-yl]carbonyl]amino]phenyl]-4-piperidineacetate (melting point 151° C.) identified as compound No. 39 in the following table F-1.
