Participants

Reaction Steps

The mixture of rac-3-bromo-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (100 mg, 0.27 mmol) (from example 1c supra), 4-propoxy-phenylamine (61 mg, 0.41 mmol) and DIPEA (104.5 mg, 0.81 mmol) in propan-2-ol (10 mL) was stirred at room temperature for 2 h. Then water (10 mL) was added and the desired product was precipitated out, then filtrated and dried to give 98 mg of rac-6-chloro-3-(3-chloro-benzyl)-3-(4-propoxy-phenylamino)-1,3-dihydro-indol-2-one as a white solid. MS: 441 (M+H)+.
