Versuchsvorschrift

5-Bromo-2-t-butyloxycarbonylamino-8-Methoxyquinoline (1.21 g) and tetrahydrofuran (20 ml) were combined at room temperature under a nitrogen atmosphere. Sodium hydride (60% dispersion in oil) (164 mg) was added and the reaction mixture stirred for 2 h whilst effervescence occurred and a yellow colour appeared. Iodomethane (0.43 ml) was then added and stirring was continued for 2 h after which time the reaction was diluted with ethyl acetate (100 ml), washed successively with water, saturated aqueous sodium bicarbonate and brine, then dried (magnesium sulphate) and evaporated in vacuo to give the title compound (1.1 g) as a yellow solid.
