実験手順

A suspension of 6-chloro-N-(6-fluoropyridin-2-yl)imidazo[1,2-b]pyridazin-8-amine (132 mg, 0.5 mmol) and pyrrolidine (54 mg, 0.75 mmol) in water (0.3 mL) was heated to 205° C. in a microwave oven for 30 minutes. The reaction mixture was purified by chromatography (silica gel, 200-300 mesh, CH2Cl2:MeOH=200:1) to give 6-chloro-N-(6-(pyrrolidin-1-yl)pyridin-2-yl)imidazo[1,2-b]pyridazin-8-amine (29 mg, 18%) as a light yellow solid. LC-MS: [M+H]+, 315.0, tR=1.837 min.
