To a solution of NaNH2, prepared starting from 200 mL of liquid NH3 and 1 g of Na (catalyst: FeCl3) there are added, in portions, 5.4 g of 3-(2-bromo-4,5-dimethoxyphenyl)propanenitrile and the reaction mixture is stirred at ambient temperature for 2 hours. After evaporating off the excess NH3, 2 g of NH4Cl and 200 mL of water are added in portions. The grey crystals formed are collected and recrystallised from ethanol to yield 2.38 g of the expected product.
