Reaktionsschritte
HOBt (245 mg, 1.8 mmol), DMAP (370 mg, 3.0 mmol), EDCI.HCl (348 mg, 1.8 mmol) followed by biphenyl-4-ylamine (307 mg, 1.8 mmol) were added to a stirred solution of 2-methyl-malonic acid monomethyl ester (200 mg, 1.5 mmol) in DMF (3 mL) and the resulting mixture was stirred at ambient temperature overnight. The reaction mixture was then diluted with water and the product was extracted with ethyl acetate. The ethyl acetate layer was washed with brine solution and concentrated under reduced pressure to afford 330 mg (77%) of N-biphenyl-4-yl-2-Methyl-malonamic acid methyl ester.
