실험 절차

To a stirred solution of isoquinoline 2-oxide (2-Im-9, 5.8 g) in 140 mL of acetonitrile, diethyl phosphoro-cyanidate (1.5 eq) was added under argon followed by slow addition of TEA (3.0 eq). The mixture was refluxed for 18 h and then extracted with DCM. The organic layer was concentrated and purified by silica column chromatography to give isoquinoline-1-carbonitrile (3-Im-9).
