Versuchsvorschrift

To a solution of N-(3,5-dichlorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide from Example 1, Step 3 (1.28 g, 3.69 mmol) in CH2Cl2 (100 ml) at room temperature was added N-bromosuccinimide (0.689 g, 3.87 mmol). The reaction was stirred for 4 hrs and then poured into water. The organic phase was washed with water (3×100 ml), and dried (Na2SO4). The solvent was evaporated in vacuo and the residue triturated with CH2Cl2 to afford the title compound as an off white solid.
