To a vial charged with 6-bromo-4-(((3R,4R)-3-ethyl-1-(methylsulfonyl)piperidin-4-yl)amino) pyrrolo[1,2-b]pyridazine-3-carboxamide (15 mg, 0.034 mmol), 3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)propanenitrile (16.68 mg, 0.068 mmol) and PdCl2(dppf)-CH2Cl2 Adduct (3.61 mg, 4.42 μmol) were added 1,4-dioxane (225 μl) and a 2M solution of potassium phosphate (50.6 μl, 0.101 mmol). The suspension was purged with nitrogen for 5 minutes. The vial was sealed and heated at 100° C. for 2 hrs. The reaction mixture was diluted with methanol (10 ml), filtered, and concentrated under reduced pressure. The crude product was purified via preparative HPLC (Column: Waters XBridge C18, 19×200 mm, 5-μm). The collected fractions were combined and dried via centrifugal evaporation, yielding 6-(1-(2-cyanoethyl)-1H-pyrazol-4-yl)-4-(((3R,4R)-3-ethyl-1-(methylsulfonyl)piperidin-4-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide (9.3 mg, 0.019 mmol, 56.9% yield) as a white solid. 1H NMR (500 MHz, 1:1 Chloroform-d/Methanol-d4) δ 8.12 (s, 1H), 7.93 (s, 1H), 7.82 (s, 1H), 7.75 (d, J=1.5 Hz, 1H), 6.91 (d, J=1.0 Hz, 1H), 4.48 (t, J=6.4 Hz, 2H), 4.11 (td, J=8.4, 4.0 Hz, 1H), 3.79-3.61 (m, 2H), 3.25-3.17 (m, 1H), 3.05 (t, J=6.4 Hz, 2H), 2.97-2.85 (m, 4H), 2.43-2.34 (m, 1H), 1.88-1.76 (m, 3H), 1.51-1.40 (m, 1H), 1.04-0.97 (m, 3H). LCMS (Method K) m/z 485.0 ([M+H]+). HPLC (Method F) Rt: 1.14 min.
