Procedure

To suspension of 82B (20 mg, 0.048 mmol) in THF was added 4-fluorophenylisocyanate (6.54 μL, 0.058 mmol). The mixture was stirred at room temperature overnight. The solvent was removed under reduced and MeOH (1 mL) was added. The mixture was sonicated and the solid was collected by filtration, rinsed with a small amount of MeOH and dried under vacuum to give 8-(ethylamino)-6-((trans-4-(((4-fluorophenyl)carbamoyl)amino)cyclohexyl)amino)-N-(3-fluoro-4-pyridinyl)imidazo[1,2-b]pyridazine-3-carboxamide (20.8 mg) as an off white solid. HPLC Rt=3.176 minutes (Chromolith SpeedROD 4.6×50 mm, 10-90% aqueous methanol containing 0.1% TFA, 4 min gradient, monitored at 220 nm). [M+H]=550.
