실험 절차

Under nitrogen atmosphere, a suspension of 5-bromoisoquinoline (252 mg), tris(dibenzylideneacetone)palladium(0) (59 mg), 2-(di-tert-butylphosphino)biphenyl (74 mg), (3-aminopropyl)methylcarbamic acid tert-butyl ester (274 mg, Asta Tech), and sodium tert-butoxide (163 mg) in toluene was stirred with heating at 70° C. for 3 hours. The reaction mixture was returned to room temperature and purified by silica gel column chromatography (n-hexane:ethyl acetate=1:1) to obtain the title compound (325 mg).
