実験手順

A suspension of 5A (80 mg, 0.245 mmol), ethanamine (0.6 mL, 1.200 mmol, 2 M/THF) and DIEA (0.086 mL, 0.491 mmol) in NMP (0.7 mL) was heated at 80° C. for 5 h. The reaction mixture was cooled to room temperature and the solid was collected by filtration and washed with a small amount of DCM to give 6-chloro-8-(ethylamino)-N-(3-fluoropyridin-4-yl)imidazo[1,2-b]pyridazine-3-carboxamide as a yellow solid 62.8 mg. HPLC Rt=2.517 minutes (Chromolith SpeedROD 4.6×50 mm, 10-90% aqueous methanol containing 0.1% TFA, 4 min gradient, monitored at 220 nm). [M+H]=335.
