Reaction Steps

Compound 454 (556 mg, 2.00 mmol) and DMAP (24.4 mg, 0.200 mmol) were suspended in pyridine (8 mL), and 2-furoyl chloride (0.394 mL, 4.00 mmol) was added thereto, followed by stirring at 50° C. for 2 hours. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (chloroform:methanol=19:1), followed by recrystallizing from ethanol to afford the entitled Compound 511 (491 mg, 66%) as a white solid.
