With hydrogenchloride; sodium hydroxide; In water; | Step A Synthesis of 2-bromo-2-propenoic acid as an intermediate A stirred solution of 84.9 grams (0.366 mole) of <strong>[600-05-5]2,3-dibromopropionic acid</strong> in an appropriate amount of water was cooled to 0+-5. To this was added dropwise 184 ml of aqueous 2N sodium hydroxide at such a rate that the reaction mixture temperature did not exceed 10. An additional 184 ml of aqueous 2N sodium hydroxide was added dropwise. Upon completion of addition, the reaction mixture was allowed to warm to ambient temperature where it was stirred for one hour. The clear reaction mixture was acidified with 47 ml of concentrated hydrochloric acid and extracted with three portions of 400 ml each of diethyl ether. The combined extracts were dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure to give a solid residue. The solid was recrystallized from hexane to give 41.6 grams of 2-bromo-2-propenoic acid; mp 69.5-71.5. |
