実験手順

A solution of the aminonitrile 3 (22.43 g, 100 mmol) in abs. ether (100 ml) was added dropwise, under argon and while cooling with ice, to a 1M solution of 4-chlorophenylmagnesium bromide in ether (200 ml, 200 mmol), and stirring was carried out for 20 h at RT. For working up the reaction mixture, saturated ammonium chloride solution (100 ml) and water (100 ml) were added, while cooling with ice, and extraction with diethyl ether (3×100 ml) was carried out. The organic phase was washed with water and saturated sodium chloride solution, dried and concentrated.
