Versuchsvorschrift
A mixture of ethyl 2-amino-2-thioxoacetate (10.1 g), 3-bromo-2-oxopropanoic acid (12.7 g) and THF (200 ml) was stirred at 50° C. overnight. The mixture was concentrated in vacuo, and the resulting solid was suspended in EtOAc. The precipitate was collected by filtration to give the title compound (7.4 g) as a white solid.
