Procedimiento

A solution of the aminonitrile 3 (2.24 g, 10 mmol) in abs. THF (10 ml) was added dropwise, under argon and while cooling with ice, to a 1M solution of thiophen-2-yl-magnesium bromide in THF (20 ml, 20 mmol), and stirring was carried out for 20 h at RT. For working up the reaction mixture, saturated ammonium chloride solution (10 ml) and water (10 ml) were added, while cooling with ice, and extraction with diethyl ether (3×10 ml) was carried out. The organic phase was washed with water and saturated sodium chloride solution, dried and concentrated.
