Versuchsvorschrift

A mixture of 2-methylene-4-morpholin-4-yl-4-oxo-butyric acid (2 g, 10.03 mmol), in DMF (5 mL), 2-trifluoromethylbenzyl mercaptan (1.93 g, 10.03 mmol) and DMAP (122 mg, 1.0 mmol) was stirred at ambient temperature for 16 hours. Methanol (200 mL) and a saturated aqueous solution of Oxone® (20 g, 32.5 mmol) were added with continued stirring for 2 hours. Methanol was removed under vacuum and the aqueous residue was diluted with 200 mL of water. The crystallized product was filtered, washed with water, and dried under vacuum to yield 4-morpholin-4-yl-4-oxo-2-(2-trifluoromethyl-benzylsulfonylmethyl)-butyric acid (0.95 g) as a white solid.
