Reaction Steps

To a solution of 6-chloro-3-(naphthalen-1-yl)imidazo[1,2-b]pyridazine (50 mg, 0.179 mmol, 1.0 equiv) in DMSO (2.0 mL) was added p-toluene sulfonic acid monohydrate (35 mg, 0.184 mmol, 1.0 equiv) and 4-aminobutan-1-ol (200 mg, 2.24 mmol, 12.5 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 30 mg of a white solid, 50%.
