実験手順
The crude compound from Step 1 was dissolved in tetrahydrofuran (0.3 M), the solution was cooled to 0° C., and sodium hydride (as a 60% dispersion in oil, 1.3 eq) was added in portions. After stirring at 0° C. for 1 hour, the mixture was allowed to warm up to room temperature. After 2 hours, water was added to the suspension and and the insoluble solid was filtered and washed copiously with water. When dry, the solid was stirred in ether at room temperature for 24 hours and filtered to afford the title compound as a cream-colored solid.
