Versuchsvorschrift

A suspension of 6-chloro-N-(3-fluoropyridin-4-yl)-8-((4-methoxybenzyl)(pyridin-2-yl)amino)imidazo[1,2-b]pyridazine-3-carboxamide 5B (0.500 g, 0.992 mmol) and (trans)-cyclohexane-1,4-diamine (1.360 g, 11.91 mmol) in NMP (2.5 mL) was subjected to 110° C. in a 300 W CEM Discover microwave for 20 min. The mixture was diluted with MeOH and purified via preparatory HPLC using a YMC ODS C-18 column (30×250 mm) 0%-100% B. Solvent B: (90% MeOH, 10% H2O, 0.1% TFA). Solvent A: (10% MeOH, 90% H2O, 0.1% TFA). Gradient, start % B=0, final % B=100, gradient time 60 min, flow rate 25 mL/min. Rt=42 min. 6-((trans)-4-aminocyclohexylamino)-N-(3-fluoropyridin-4-yl)-8-((4-methoxybenzyl)(pyridin-2-yl)amino)imidazo[1,2-b]pyridazine-3-carboxamide (0.500 g, 54.6% yield) was obtained as a light yellow solid. LC/MS, m/z 582.1 (M+1). HPLC Rt=3.211 min. YMC S5 ODS-A column (4.6×50 mm) 0%-100% B. Solvent B: (90% MeOH, 10% H2O, 0.2% H3PO4). Solvent A: (10% MeOH, 90% H2O, 0.2% H3PO4). Gradient, start % B=0, final % B=100, gradient time 4 min, hold at 100% 1 min, flow rate 4 mL/min. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.20 (1H, d, J=1.76 Hz), 8.69 (1H, d, J=2.77 Hz), 8.46-8.53 (1H, m), 8.41-8.47 (1H, m), 8.28 (1H, dd, J=4.78, 1.26 Hz), 8.01 (1H, s), 7.89 (2H, d, J=4.28 Hz), 7.57-7.72 (1H, m), 7.26 (2H, d, J=8.81 Hz), 7.18 (1H, d, J=7.81 Hz), 7.11 (1H, d, J=8.31 Hz), 7.03 (1H, dd, J=6.55, 5.04 Hz), 6.83 (2H, d, J=8.81 Hz), 6.52 (1H, s), 5.43 (2H, s), 3.72-3.84 (1H, m), 3.64-3.72 (3H, s), 3.06 (1H, d, J=4.78 Hz), 2.03-2.15 (2H, m), 1.95 (2H, d, J=10.07 Hz), 1.34-1.49 (2H, m), 1.26 (2H, d, J=12.34 Hz).
