Reaction Steps

A 1 M solution of NaHMDS in THF (167.5 mL, 167.5 mmol) was slowly added to a solution of 5-bromo-2-chloro-N-{2-(ethylamino)-6-choro-3-pyridinyl}-3-pyridinecarboxamide (28.4 g, 72.8 mmol) in pyridine (146 mL) heated to 50° C. The reaction mixture was stirred at 50° C. for 1.5 h. The mixture was then poured into a mixture of water and ice (1 L) and, after 1 h, the resulting suspension was filtered. The solid was washed with water and dried under reduced pressure to give the title compound (23.4 g, 91% yield).
