실험 절차
To bromoacetic acid (500 g, 3.60 mol) and ice (400 g) was added dropwise 40% sodium hydroxide (375 g, 3.75 mol) at below 20° C. Acetone oxime (239 g, 3.27 mol) was added. At below 20° C., 40% sodium hydroxide (375 g, 3.27 mol) was added dropwise. The reaction mixture was allowed to warm to room temperature overnight and extracted with 500 ml of ether. The aqueous phase was acidified to pH 2 and extracted with ether (3×500 ml). The combined organic layers were dried over MgSO4, filtered, and concentrated to dryness. Hexane (250 ml) was added to the residue and the precipitate was collected to give the title compound.
