実験手順
Compound 33 (520 mg; 1.66 mmol) was dissolved in pyridine (6 ml), and phosphorus oxychloride (1.27 g; 8.3 mmol) was added thereto. The mixture was stirred for 1 hour at 130-140° C., and then cooled. The reaction mixture was poured into water, and alkalinized with sodium hydroxide pellet. The mixture was extracted with ether (120 ml), and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=20:1), to thereby yield 420 mg of the target compound (yield: 85.7%).
