The ethanol solvent is then removed by evaporation under vacuum and the residue poured into 100 ml. of water and extracted three times with ethyl ether. The aqueous solution is acidified to about pH 2 with 5N aqueous hydrochloric acid and then extracted three times with ethyl ether. The ethyl ether extracts are combined and dried over anhydrous magnesium sulfate, filtered and the filtrate evaporated under vacuum to remove the ethyl ether, affording exobicyclo[3.1.0]hex-2-yl acetic acid as a residue.
