Reaction Steps

A mixture of 6-(1-(6-bromo-[1,2,4]triazolo[4,3-a]pyridin-3-yl)ethyl)pyridazin-3-amine (1.0 g, 3.13 mmol), 2-bromoacetonitrile (0.251 ml, 3.76 mmol) and NaHCO3 (0.053 g) in IPA (10 mL) was heated at 100° C. in a sealed tube for 2 hrs. The solid was filtered off, rinsed with IPA, and stripped to dryness via rotary evaporation. The resulting residue was purified by LCMS and lyophilized as a TFA salt to provide the title compound, 6-(1-(6-bromo-[1,2,4]triazolo[4,3-a]pyridin-3-yl)ethyl)imidazo[1,2-b]pyridazin-2-amine 48G (0.62 mg, 1.73 mmol, 55%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.85 (d, J=7.07 Hz, 3 H) 5.17 (d, J=7.07 Hz, 1 H) 7.38-7.57 (m, 3 H) 7.80 (d, J=9.60 Hz, 1 H) 7.99 (d, J=9.09 Hz, 1 H) 8.78 (s, 1 H). ESI-MS:m/z 358.1 (M+H)+.
