Reaction Steps

Following a procedure described in J. Med. Chem. 2002, 45, 382-389; 0.44 g (2.7 mmol) 3-(4-fluoro-phenyl)-3-oxo-propionitrile (the preparation of which is described in example 17), 0.33 g (2.15 mmol) [1,4]dithiane-2,5-diol, 0.16 ml (2.15 mmol) diethyl-amine 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 0.41 g (69%) (2-amino-thiophen-3-yl)-(4-fluoro-phenyl)-methanone as a light brown crystals.
