실험 절차

2.0 g (5.4 mmol) of (9S)-7-acetoxy-10-acetyl-2,3-dimethyl-9-phenyl-9,10-dihydroimidazo[1,2h][1,7]-naphthyridine are dissolved in 30 ml of acetone and 6 ml of water. 1.0 g (6.4 mmol) of potassium permanganate is then introduced in portions at 0° C. After 30 min, the brown suspension is admixed with 1 ml of saturated sodium hydrogensulphite solution, filtered through Celite and washed with methanol and dichloromethane. The filtrate is concentrated and the residue crystallized using ethanol. 0.3 g (16%) of the title compound is isolated as a yellow solid (m.p. 192° C.).
