Reaction Steps

A flask was charged with (S)-3-(2,6-difluoro-4-(methylsulfonyl)phenylamino)-1,4′-bipiperidin-2-one hydrochloride (0.250 g, 0.590 mmol), 2,5-dichloropyrazine (0.105 g, 0.708 mmol), Hunig's base (0.309 mL, 1.77 mmol), and DMF (5 mL). The reaction mixture was stirred at 100° C. overnight. The organic solvents were removed under reduced pressure. The residue was purified using silica gel column chromatography eluting with ethyl acetate to provide (S)-1′-(5-chloropyrazin-2-yl)-3-(2,6-difluoro-4-(methylsulfonyl)phenylamino)-[1,4′-bipiperidin]-2-one (0.102 g, 0.204 mmol, 34.6% yield) as light yellow solid. Mass spectrum (apci) m/z=500.1 (M+H).
