Reaction Steps

To a solution of 420 mg of tert-butyl 4-[(2-acetylhydrazino)carbonyl]-2,2,4-trimethyl-1,3-oxazolidine-3-carboxylate in 13 ml of toluene was added 309 mg of 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide, followed by stirring at 110° C. for 5 hours. The reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 228 mg of tert-butyl 2,2,4-trimethyl-4-(5-methyl-1,3,4-thiadiazol-2-yl)-1,3-oxazolidine-3-carboxylate.
