Reaction Steps

N-(3′-Fluoro-5,6′-dimethyl-2,2′-bipyridin-4-yl)-1H-pyrazolo[4,3-b]pyridin-7-amine (81 mg, 0.242 mmol) was combined with acetonitrile (2.4 mL) and isocyanatoethane (23.78 μl, 0.303 mmol) along with 1 drop of pyridine. The mixture was heated at 75° C. The reaction was then cooled to give a solid which was collected by filtration, rinsed with acetonitrile to give the title compound. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.35 (3H, t, J=7.20 Hz) 2.47 (3H, s) 2.64 (3H, s) 3.51-3.63 (2H, m) 7.17-7.23 (1H, m) 7.33 (1H, d, J=4.55 Hz) 7.43 (1H, dd, J=10.48, 8.46 Hz) 7.51-7.59 (1H, m) 8.08 (1H, br. s.) 8.27 (1H, s) 8.41 (1H, d, J=5.31 Hz) 8.65 (1H, br. s.) 11.00 (1H, br. s.). MS [M+H] found 406.4.
