Versuchsvorschrift

α-Chlorosulfonyl(2,3-dihydro-5-benzofuranyl)acetic acid (5 mmole) is added to 30 ml of ethyl ether. To this mixture is added 5 mmole of ethanol in 10 ml of ethyl ether which contains 10 mmole of triethylamine. The mixture is stirred at 20° C. for about 1 hour and 50 ml of water is added. The pH is adjusted to about 6.5 and the layers separated. The organic layer is dried over magnesium sulfate, filtered and evaporated to give α-ethoxysulfonyl(2,3-dihydro-5-benzofuranyl)acetic acid.
