実験手順

To a suspension of 2-((3-(1-(azetidin-3-yl)piperidin-4-yl)-2-chloro-5-cyanophenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 318) (25 mg, 0.051 mmol) and triethylamine (0.014 mL, 0.102 mmol) in CH2Cl2 (1.5 mL) was added dropwise acetyl chloride (4.41 mg, 0.056 mmol, diluted with DCM, 10V % in DCM, 44 uL) at 0° C. The suspension converted to a clear solution in a few min, and continued stirring at 0° C. for 1 h. Removal of the solvent, and the crude material was purified via preparative LC/MS with the following conditions: Column: Waters XBridge C18, 19×200 mm, 5-μm particles; Mobile Phase A: water with 20-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: water with 20-mM ammonium acetate; Gradient: 20-60% B over 20 minutes, then a 5-minute hold at 100% B; Flow: 20 mL/min. Fractions containing the desired product were combined and dried via centrifugal evaporation left the titled product (15.6 mg)
