Reaction Steps

To a mixture of 6.96 g of tert-butyl (4R)-4-cyano-2,2,4-trimethyl-1,3-oxazolidine-3-carboxylate, 12.5 g of triethylamine hydrochloride, and 105 ml of toluene was added 5.84 g of sodium azide, followed by stirring at 103° C. for 3 hours. The insoluble materials were separated by filtration and the filtrate was concentrated. The obtained residue was purified twice by silica gel column chromatography to obtain 7.65 g of tert-butyl (4R)-2,2,4-trimethyl-4-(2H-tetrazol-5-yl)-1,3-oxazolidine-3-carboxylate.
