실험 절차

The product from Example 277B (100 mg, 0.287 mmol) in THF (2 mL) was treated with NaH (95%, 8.7 mg, 0.344 mmol). After stirring at room temperature for 20 minutes, the mixture was treated with methyl iodide (1.2 eq, 21.4 μL) and stirred for 1 hour. The mixture was concentrated under reduced pressure and CH2Cl2 (10 mL) was added. The organic layer was washed with water (5 mL×3), dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure to provide the title compound.
