Reaction Steps
A mixture of 3-(3,5-dichloro-4-formylphenyl)-propionic acid tert butyl ester (440 mg, 0.8 mmol), 3,4-diamino-N-quinolin-2-yl-benzamide (403 mg, 1 eq) and oxone (600 mg, 0.67 eq) in DMF (10 mL)/H2O (1 mL) was stirred vigorously open to air for 1 h. The mixture was partitioned between water and ethyl acetate. The ethyl acetate fractions were dried over magnesium sulphate and the solvent was removed under reduced pressure. The residue was purified by silica gel chromatography to give 3-{3,5-dichloro-4-[6-(quinolin-2-ylcarbamoyl)-1H-benzoimidazol-2-yl]-phenyl}-propionic acid tert-butyl ester as an orange foam. 1H-NMR (CDCl3, 400 MHz): δ 8.60 (d, J=8.97 Hz, 1H), 8.38 (s, 1H), 8.21-8.29 (m, 1H), 7.95 (dd, J=8.34, 1.26 Hz, 1H), 7.82-7.91 (m, 2H), 7.71 (ddd, J=8.37, 6.98, 1.33 Hz, 2H), 7.47-7.56 (m, 1H), 7.17-7.24 (m, 2H), 2.85 (t, J=7.33 Hz, 2H), 2.50-2.57 (m, 2H), 1.42-1.48 (m, 10H).
