実験手順

DIPEA (216 mg, 0.3 mL, 1.6 mmol) was added to a stirred solution of [(biphenyl-4-carbonyl)-methyl-amino]-acetic acid (100 mg, 0.37 mmol) in DMF (3 mL). HOBT (55.2 mg, 0.4 mmol) and EDCI (178 mg, 0.92 mmol) were then added at room temperature. After 2 minutes piperazin-1-yl-(2-trifluoromethyl-phenyl)-methanone hydrochloride salt (131 mg, 0.44 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was then added and filtered the solid precipitated out to afford 135 mg (71.3% yield) of biphenyl-4-carboxylic acid methyl-{2-oxo-2-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethyl}-amide. LCMS Purity: 96.56%. 1H NMR (DMSO-d6): δ 7.9-7.6 (m, 7H), 7.6-7.45 (q, 4H), δ 7.45-7.3 (q, 2H), 4.5-4.2 (m, 2H), 4.15 (s, 1H), 3.8-3.5 (m, 4H), 3.5-3.4 (m, 2H), 3.25-3.1 (m, 2H), 3.0 (s, 3H).

後処理
