Reaction Steps

At room temperature, 2-Amino-3-ethoxy-benzoic acid (0.59 g, 3.26 mmol), 3-Bromo-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (1.21 g, 3.26 mmol) and DIPEA (0.68 ml) were mixed in about 6 ml CH2Cl2. After stirred overnight, the solution was concentrated and the crude product was purified by chromatography to obtain 400 mg solid rac-2-[6-Chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-ylamino]-3-ethoxy-benzoic acid. MS: 471 (M+H)+.
