실험 절차

A solution of methyl 1-{2-[[(benzyloxy)carbonyl](methyl)amino]ethyl}-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (0.5 g, 1.21 mmol) in MeOH (6 mL) was treated with Hunig's base (0.33 mL, 1.82 mmol) and 1-[4-fluoro-2-(methylsulfonyl)phenyl]methanaminium chloride (0.35 g, 1.46 mmol) and heated in a sealed reaction vessel at 80 degrees C. After overnight, an additional 0.5 equivalents of the amine and 1.5 equivalents of Hunig's base was added and the reaction heated until HPLC showed the starting material gone. The reaction was cooled and the solids that percipitated were collected by filtration to give pure product.
