Reaction Steps

A slurry of N-(3,6-dichloropyridin-2-yl)pivalamide (1.83 g, 7.41 mmol) in 75 mL 5N aq HCl with water cooled reflux pyridine was heated in a 115° C. bath overnight, to give a clear yellow solution. The reaction mixture was cooled and poured onto ice, and was basified with 10 N NaOH. The resulting white precipitate was extracted with DCM, and the combined organics were dried over anhydrous sodium sulfate, filtered, and concentrated in vauco to give 3,6-dichloropyridin-2-amine as an off-white solid. MS (ESI) m/z: calculated: 162.0; Observed: 163.0 (M++1).
