A solution of the aminonitrile 4 (2.24 g, 10 mmol) in absolute THF (10 ml) was added dropwise to a 1 M solution of thiophen-2-yl-magnesium bromide in THF (20 ml, 20 mmol) under argon and while cooling with ice, and the mixture was stirred at RT for 20 hours. The reaction mixture was worked up by adding saturated ammonium chloride solution (10 ml) and water (10 ml) while cooling with ice, and extracting the mixture with diethyl ether (3×10 ml). The organic phase was washed with water and saturated sodium chloride solution, dried and concentrated.
