Reaction Steps

4-[(7-Oxo-5,6,7,8-tetrahydro[1,8]naphthyridin-4-yl)oxy]aniline (43 mg), p-fluorophenyl isocyanate (28 mg), tetrahydrofuran (5 ml) and dimethylformamide (2 ml) were stirred at room temperature for 30 minutes. Water was added dropwise at room temperature until precipitation of crystals, and these were filtered out to obtain 48 mg of the target substance as white crystals.
