PROCEDURE

实验过程

(R)-3-methanesulfonyloxy-2-methyl-propionic acid methyl ester was dissolved in 100 mL of dimethylformamide, and then 8.2 g (126 mmol) of sodium azide was added thereto at 60° C., followed by stirring for 24 hours. After addition of 400 mL of ethylacetoacetate and washing with water, an organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and then the residue was purified by column chromatography to give 2 g (13.9 mmol) of the title compound in a yield of 32%.
