Versuchsvorschrift

To the stirred solution of the azide (500 mg, 2.27 mmol, Example 304) in tetrahydrofuran (8 mL) at 0° C., sodium hydride (60% in oil dispersion, 180 mg, 4.54 mmol, Aldrich) was added slowly and the mixture was stirred for 30 minutes. Methyl iodide (184 uL, 2.95 mmol, Aldrich) was then added and the mixture was stirred at room temperature overnight. The reaction was quenched with saturated ammonium chloride solution and the mixture was extracted with ethyl acetate. The extract was washed with brine and dried with sodium sulfate. The solvent was removed and the residue was purified by chromatography (15% ethyl acetate/hexanes first and then 35%) to give a yellow oil. 280 mg, 53%.
