Reaction Steps

To a solution of 4-((R)-1-(1-methylcyclopropyl)ethylamino)-6-(5-(methylsulfinyl)-1,3,4-oxadiazol-2-yl)pyrrolo[1,2-b]pyridazine-3-carboxamide (16.00 mg, 0.041 mmol) in NMP (0.5 mL, 0.082M) was added 4-(2-aminoethyl)morpholine (26.80 mg, 0.206 mmol) followed with DIPEA (0.029 mL, 0.165 mmol) and stirred at 130° C. for 30 min in a Biotage Initiator microwave. The reaction mixture was dissolved in 1.5 mL of DMF and directly purified on Reverse Phase HPLC to yield desired product (2.23 mg, 12% yield). MS (ES+) m/z: 454.87 (M+H); HPLC: 92% retention time: 1.57 min (analytical HPLC Method B).
