実験手順

A solution of 6-bromo-4-(((3S,4S)-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide hydroiodide (250 mg, 0.536 mmol), 6-bromonicotinonitrile (103 mg, 0.563 mmol) and potassium carbonate (222 mg, 1.609 mmol) in N,N-dimethylformamide (3 mL) was heated at 100° C. in a sealed tube for 90 min. The resulting mixture was cooled to room temperature, triturated with water and filtered. The filter cake was washed with water and dried under vacuum to give 6-bromo-4-(((3S,4S)-1-(5-cyanopyridin-2-yl)-4-methylpyrrolidin-3-yl)amino)pyrrolo[1,2-b]pyridazine-3-carboxamide (0.228 g, 97% yield). 1H NMR (400 MHz, 1:1 mixture of chloroform-d/methanol-d4) δ ppm 8.39-8.27 (m, 1H), 8.08 (s, 1H), 7.69-7.57 (m, 2H), 6.95-6.82 (m, 1H), 6.48 (d, J=9.0 Hz, 1H), 4.83 (br. s., 1H), 4.01-3.69 (m, 3H), 3.39 (t, J=9.6 Hz, 1H), 2.81 (br. s., 1H), 1.27 (d, J=6.8 Hz, 3H); MS (ES+) m/z: 440.2 (M+H); LC retention time: 3.885 min (analytical HPLC Method H).
