実験手順

A solution of 2-{[1-(4-azido-5-fluoropyridin-3-yl)-meth-(E)-ylidene]-amino}-3-chloro-5-fluorobenzonitrile (1.67 g, 5.25 mmol) in anhydrous toluene (25 mL) was heated under reflux for 4.5 hours. The resultant mixture was allowed to cool to room temperature and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (0-5% methanol in DCM) to afford the title compound as a yellow solid (1.41 g, 93% yield). LCMS (Method C): RT=2.71 min, m/z: 291 [M+H+].
