Reaction Steps

A mixture of 4-aminocyclohexane-1-sulfonamide (200 mg, 1.12 mmol), 6-chloro-3-(3-chlorophenyl)imidazo[1,2-b]pyridazine (200 mg, 0.76 mmol) and KF (500 mg, 8.6 mmol) in DMSO (2 mL) was heated at 120° C. overnight. LCMS showed the reaction was complete. The mixture was poured into brine (80 mL) and extracted with EtOAc (30 mL×3). The combined extracts were dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by to prep. HPLC give two isomers: EX. 8-81 isomer 1 (7.0 mg) and EX. 8-81 isomer 2 (8.1 mg) as white solid.
