Versuchsvorschrift

A mixture of 3-[2-amino-4-(4-chlorophenyl)-5-thiazolyl]propionic acid (2.67 g), diethyl cyanophosphate (1.69 g), thiomorpholine-1,1-dioxide hydrochloride (1.62 g), triethylamine (2.9 ml) and N,N-dimethylformamide (40 ml) was stirred at room temperature for 3 hrs. The reaction mixture as poured into water, extracted with ethyl acetate, washed with 0.1N aqueous sodium hydroxide solution and water, dried over anhydrous magnesium sulfate and concentrated. The precipitated solid was collected by filtration to give 4-{3-[2-amino-4-(4-chlorophenyl)-5-thiazolyl]propanoyl}thiomorpholine-1,1-dioxide as a colorless powder. Recrystallization from ethanol-isopropyl ether gave colorless prism crystals. melting point: 220–222° C.
