Participants

Reaction Steps

I-Amino-propan-2-ol (2.44 g, 30.3 mmol) and triethylamine (0.42 mL, 3.03 mmol) were added to a solution of 4-(4-bromo-2-chlorophenylamino)-5,6-dichloronicotinic acid tert-butyl ester (1.37 g, 3.03 mmol) in acetonitrile (30 mL). The reaction was heated to reflux. After 23 hours the reaction was cooled to room temperature and diluted with EtOAc, washed with saturated NaHCO3, water, brine, dried over Na2SO4 and concentrated to a white solid. Purification by flash column chromatography (20:1 dichloromethane/methanol) provided the desired product as a white solid (1.11 g, 75%). MS APCI (+) m/z 492, 494 (M+, Cl, Br pattern) detected.
