실험 절차

Ethyl 8-chloro-1,6-dimethyl-4-oxo-1,4-dihydro[1,7]naphthyridine-3-carboxylate (Preparation 44, 0.62 g) and N-bromosuccinimide (0.45 g) are dissolved in dichloro-ethane (100 mL). The solution is subjected to light by shining a 650 W sunlamp with stirring for 25 minutes. Solvent is evaporated and the crude solid obtained is dissolved in DMF (15 mL). Morpholine (0.86 g) is added and the mixture stirred for 18 hours. The mixture is poured into CH2Cl2 (200 mL) and then washed with water (3×200 mL). The organics are dried with Na2SO4, filtered and the solvent evaporated. The crude solid is chromatographed with MeOH/CH2Cl2 (0-5%) to obtain 0.32 g (40%) of the title compound as a light orange solid. Physical characteristics: MS (ESI+) m/z 366 (M+H).
