Versuchsvorschrift

Compound 353 (105 mg, 0.288 mmol) was dissolved in DMF (1.4 mL), and 55% sodium hydride (25.3 mg, 0.576 mmol) and methyl iodide (0.0179 mL, 0.288 mmol) were added thereto, followed by stirring at room temperature 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 (hexane:ethyl acetate=1:1) to afford the entitled Compound 354 (97.0 mg, 89%).
