実験手順

HOBt (60 mg, 0.44 mmol), DIPEA (140 mg, 1.1 mmol), EDCI.HCl (85 mg, 0.44 mmol) followed by (2-bromo-phenyl)-piperazin-1-yl-methanone hydrochloride (136 mg, 0.44 mmol), were added to a stirred solution of N-biphenyl-4-yl-2-methyl-malonamic acid (100 mg, 0.37 mmol) in DMF (2.0 mL). The resulting mixture was stirred at ambient temperature overnight then diluted with water. The product was extracted with ethyl acetate. The ethyl acetate layer was washed with brine and concentrated under reduced pressure to afford 140 mg (73%) of N-biphenyl-4-yl-3-[4-(2-bromo-benzoyl)-piperazin-1-yl]-2-methyl-3-oxo-propionamide. LCMS: 520.12 (M+1)+, 97.32%, 1H NMR (DMSO-d6): δ 10.2 (d, 1H), 7.8-7.3 (m, 13H), 4.0-3.4 (m, 7H), 3.2-3.0 (m, 2H), 1.3 (m, 3H).
