Reaction Steps

To 500 ml of liquid NH3 was added 35.4 g (0.2 mol) of 3,4-dimethoxyphenylacetonitrile and 11.7 g (0.3 mol) of NaNH2. The mixture was stirred for two hours, maintaining a temperature at -25° to -30°C by cooling in a dry ice/acetone bath. 4-Chloroquinoline (16.4 g, 0.1 mol) was added and the resulting mixture was allowed to stir at room temperature until all excess NH3 had evaporated. Benzene was added to the residue and water was added slowly to destroy excess NaNH2. The phases were separated and the aqueous phase was extracted with benzene. The combined benzene extracts were extracted with 9M HCl (2×150 ml). The acidic phase was washed with Et2O (500 ml), cooled and basified with concentrated NH4OH. The aqueous mixture was extracted with CHCl3 (500 ml). The CHCl3 extract was dried with MgSO4 and evaporated to give a quantitative yield of crude α-(4 -quinolinyl)-α-(3,4-dimethoxyphenyl)acetonitrile intermediate.
