実験手順

To a solution of 3-(tert-butoxycarbonylamino)-5-methoxyquinoline (2.74 g, 10 mmol) in aqueous 48% HBr (40 mL), NaNO2 (2.1 g, 30 mmol) in water (20 mL) is added at 0° C. The reaction mixture is stirred 1 hour. The reaction mixture is extrated with CH2Cl2 (3×30 mL). After drying over MgSO4, dichloromethane is evaporated affording the title compound.
