Procedure

Compound 296 (697 mg, 1.73 mmol) was dissolved in dichloromethane (10 mL), and DMP (848 mg, 2.00 mmol) was added thereto, followed by stirring at room temperature for 1 hour. Methanol (10 mL) was added to the reaction mixture, followed by stirring for 10 minutes, and the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=1:1) to afford the entitled Compound 297 (632 mg, 91%).
