実験手順

DIPEA (118 mg, 0.16 mL, 0.92 mmol) was added to a stirred solution of 2-fluoro-6-trifluoromethyl-benzoic acid (48 mg, 0.23 mmol) in DMF (2 mL). HOBT (46 mg, 0.35 mmol) and EDCI (100 mg, 0.57 mmol) were then added at room temperature. After 2 minutes, Biphenyl-4-carboxylic acid (2-oxo-2-piperazin-1-yl-ethyl)-amide (75 mg, 0.23 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was then added and the product was extracted with EtOAc and the organic layer was washed with brine. The organic phase was dried over Na2SO4 and concentrated under reduced pressure to get the residue. The obtained residue was purified by column chromatography (using basic alumina and 10% MeOH in CHCl3 as eluent) to afford 60 mg (50.8% yield) of biphenyl-4-carboxylic acid {2-[4-(2-fluoro-6-trifluoromethyl-benzoyl)-piperazin-1-yl]-2-oxo-ethyl}-amide. LCMS Purity: 96.5%. 1H NMR (CDCl3): δ 7.9 (m, 2H), 7.6 (m, 6H), 7.4 (m, 4H), 4.3 (m, 2H), 3.8 (m, 3H), 3.8 (m, 3H), 3.6-(m, 2H), 3.5 (m, 1H) 3.3 (m, 2H).
