Reaction Steps

To a solution of 6-chloro-3-(thieno[3,2-b]pyridin-2-yl)imidazo[1,2-b]pyridazine (40 mg, 0.139 mmol, 1.0 equiv) in DMSO (2.0 mL) was added p-toluene sulfonic acid monohydrate (20 mg, 0.139 mmol, 1.0 equiv) and trans-4-aminocyclohexanol (0.695 mmol, 5.0 equiv) and heated to 100° C. for 24 h. The reaction mixture was diluted with water and extracted with ethyl acetate. Purification by column chromatography using 5% methanol in dichloromethane elution gave 40 mg of the yellow solid, 79%.
