Reaction Steps

To a mixture of 6 g. (0.034 moles) of 5-methyl-1,2,4,5-tetrahydro-3H-2-benzazepin-3-one and 4 drops of Triton B (benzyltrimethylammonium hydroxide) in 10 ml. of pyridine, are added dropwise 2 g. (0.038 moles) of acrylonitrile dissolved in 2.5 ml. of pyridine. The reaction mixture is heated to 80° C. for 2 hours and then poured into iced water. It is acidified with hydrochloric acid to pH 4 and extracted with chloroform. The organic phase is washed neutral with water and then dried over anhydrous sodium sulfate. It is filtered and the solvent is evaporated off in vacuo. 8 g. (almost theoretical yield) of syrupy 2-(2-cyanoethyl)-5-methyl-1,2,4,5-tetrahydro-3H-2-benzazepin-3-one are obtained.
