Versuchsvorschrift

Following a procedure described in J. Med. Chem. 2002, 45, 382-389; 1.45 g (10 mmol) 3-oxo-3-phenyl-propionitrile, 0.76 g (5.0 mmol) [1,4]dithiane-2,5-diol, 0.40 ml (10 mmol) diethylamine and 5 ml ethanol were charged in a sealed tube. The reaction mixture was heated at 50° C. for 6 h. The tube was then placed in a fridge (about 4° C.) for the night, and the product was collected by filtration and dried under vacuum to afford 0.42 g (23%) (2-amino-thiophen-3-yl)-phenyl-methanone as a light brown crystals. ES-MS m/e (%): 204 (M+H+, 100).
