Reaction Steps

N,N-Diisopropylethylamine (0.032 mL, 0.181 mmol), acetic anhydride (6.26 μL, 0.066 mmol), 6′-[(3S)-3-aminopyrrolidin-1-yl]-4-methyl-N-[4-(trifluoromethyl)pyridin-2-yl]-2,3′-bipyridin-6-amine (Example 5, 25 mg, 0.060 mmol), and THF (1 mL) were added to a flask and stirred at room temperature for 16 hours. The crude solution was purified via reverse phase high pressure liquid chromatography to afford N-[(3S)-1-(4-methyl-6-{[4-(trifluoromethyl)pyridin-2-yl]amino}-2,3′-bipyridin-6′-yl)pyrrolidin-3-yl]acetamide. MS ESI calcd. for C23H24F3N6O [M+H]+ 457. found 457. 1H NMR (500 MHz, DMSO-d6) δ 10.08 (s, 1H), 8.76 (s, 1H), 8.60 (s, 1H), 8.47 (d, J=5.0 Hz, 1H), 8.11 (m, 1H), 7.24 (s, 1H), 7.17 (d, J=5.0 Hz, 1H) 7.12 (s, 1H), 6.46 (d, J=8.8 Hz, 1H), 3.52-3.60 (m, 3H), 3.43 (m, 1H), 3.12 (m, 1H), 2.30 (s, 3H), 2.05 (s, 1H), 1.87-1.80 (m, 2H), 1.72 (s, 1H). rhSyk IC50=17 nM.
