Reaction Steps

A mixture of 6-bromo-4-(((3R,4S)-4-fluoro-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide hydroiodide (100 mg, 0.207 mmol), 1-cyanocyclopropanecarboxylic acid (27.5 mg, 0.248 mmol), Hunig's base (0.144 mL, 0.826 mmol) and BOP (110 mg, 0.248 mmol) in N,N-dimethylformamide (2 mL) was stirred at room temperature for 2 h. The resulting mixture was diluted with ethyl acetate (80 mL) and washed with saturated NaHCO3, water, brine, dried (MgSO4) and concentrated to give crude 6-bromo-4-(((3R,4S)-1-(1-cyanocyclopropanecarbonyl)-4-fluoro-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide (70 mg), which was taken to the next step without purification. MS (ES+) m/z: 449.0 (M+H).
