Procedure

tert-Butyl 3-oxoazetidine-1-carboxylate (1 g) and THF (20 ml), which had been cooled to 0° C., were mixed, and a 1.12M methylmagnesium bromide/THF solution (10 ml) was added thereto, followed by stirring at the same temperature for 1 hour. Water and EtOAc were added to the reaction mixture, the organic layer was dried over Na2SO4, and the solvent was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain tert-butyl 3-hydroxy-3-methylazetidine-1-carboxylate (1.0 g).
