실험 절차

8-Methoxy-10,10-dimethyl-5,10-dihydro-11-oxa-4-aza-benzo[b]fluorene (Compound GT15-3, 22 mg) was dissolved in MeCN (0.26 ml) and water (0.13 ml), added with sodium chlorite (14 mg) and N-hydroxyphthalimide (2.6 mg), and the mixture was stirred at 40° C. for 1 hr. The reaction mixture was diluted with ethyl acetate. The organic layer was washed with saturated aqueous solution of sodium bicarbonate and saturated brine, and then concentrated under reduced pressure. The resulting residues were purified by silica gel column (ethyl acetate/hexane) to obtain the title compound (16 mg, 70%).
