Reaction Steps

A solution of 5-bromo-2-chloro-3-pyridinecarbonyl chloride (30.0 g, 97.0 mmol) in MeCN (100 mL) was added via cannula to a solution of 3-amino-6-chloro-2-(ethylamino)pyridine (16.6 g, 97.0 mmol) in MeCN (180 mL) containing solid NaHCO3 (14.2 g, 169 mmol) at room temperature. The mixture was stirred at room temperature for 1 h. Water (200 mL) was added and the mixture was stirred for 10 min. The resulting suspension was filtered. The solid was washed with Et2O (50 mL) and concentrated from pyridine solution (3×50 mL) to give the title compound (28.4 g, 75% yield).
