Conditions

Temperature: 180 °C

Procedure

To a solution of 6-chloro-3-(3-chlorophenyl)imidazo[1,2-b]pyridazine (200 mg, 0.78 mmol) and (S)-Piperidin-3-amine (290 mg, 2.12 mmol) in NMP (1.0 mL) was added NaHCO3 (118 mg, 1.52 mmol), the mixture was stirred at 180° C. for 60 mins under microwave irridation. The mixture was purified by flash chromatograph to give (S)-1-(3-(3-chlorophenyl)imidazo[1,2-b]pyridazin-6-yl)piperidin-3-amine (32 mg, 0.098 mmol, 13%) as a pale yellow solid.
