Procedure
A mixture of trans-N1-(3-(3-chlorophenyl)imidazo[1,2-b]pyridazin-6-yl)cyclohexane-1,4-diamine (50 mg, 0.146 mmol) and ethyl formate (0.37 mL) in DMF (1.2 mL) was heated at 90° C. for 6 h. LCMS showed the reaction was complete. The mixture was concentrated in vacuo and purified b prep-HPLC to give EX. 8-83 (22 mg, 41%) as an off-white solid.
