Reaction Steps

A mixture of (R)-3-(5-fluoro-4-(piperidin-3-ylamino)pyrimidin-2-ylamino)pyridin-2(1H)-one (Preparation 22c, 50 mg, 0.16 mmol) and 3-bromo-4H-1,2,4-triazole (prepared as described in J. Med. Chem. 2004, 47(19), 4645, 12.2 mg, 0.08 mmol) was stirred and heated overnight at 150° C. The reaction mixture was cooled to ambient temperature and diluted with methanol. Diethyl ether was then added and the precipitate that formed was filtered. The filtrate was concentrated under reduced pressure and the resulting semisolid was suspended in diethyl ether and filtered to yield the title compound (12 mg, 40%) as a yellow solid.
