実験手順

A mixture of intermediate (7) (0.025 mole) in methanol (250 ml) was hydrogenated at 50° C. overnight with Pd/C 10% (2 g) as a catalyst. After uptake of hydrogen (1 equivalent), the catalyst was filtered off and the filtrate was evaporated. The residue was triturated in DIPE. The precipitate was filtered off and dried. A part (0.2 g) of this fraction was purified by high performance liquid chromatography over RP-18 (eluent: (NH4OAc 0.5%/CH3CN 90/10)/CH3OH/CH3CN 75/25/0, 0/50/50, 0/0/100 and 75/25/0; column: Hyperprep RP 100 Å 8 μm). The pure fractions were collected and the solvent was evaporated, yielding 0.119 g of N-[4-(4-piperidinyl)phenyl]-4′-(trifluoromethyl)-[1,1′-biphenyl]-2-carboxamide acetate (1:2) (intermediate 8, melting point 150° C.).
