Versuchsvorschrift

0.5 g (0.0012 mol) of N-[2-(4-carboxymethoxyphenyl)-1-methylethyl]-2-(2-trifluoromethyl-thiazol-4-yl)morpholine is dissolved in 150 ml of chloroform and, while stirring, 2 ml ethanol and 0.25 g of concentrated sulphuric acid are added, and the mixture is heated to reflux with a water trap for one hour. The mixture is then cooled, ice-water is added, the mixture is made alkaline with ammonia and the phases are separated. The aqueous phase is then extracted again by shaking with chloroform, and the organic phase is dried over sodium sulphate, filtered and evaporated to dryness. The resulting residue is dissolved in ether, ethereal hydrochloric acid is added, the mixture is evaporated to dryness, and the residue is triturated with acetone and filtered off with suction.
