Participants

Reaction Steps

A solution of 2.1 g. (0.0092 moles) of 2-(2-cyanoethyl)-4-methyl-1,2,4,5-tetrahydro-3H-2-benzazepin-3-one in 5 ml. of 35% hydrochloric acid is heated for 30 minutes at 40° C., while stirring. The reaction mixture is poured into 30 ml. of water and the pH adjusted to 9 by the addition of sodium carbonate, with vigorous stirring. The precipitate formed is washed with water, dried and then recrystallized from diisopropyl ether. 1.5 g. (66% of theory) of 2-(2-carbamoylethyl)-4-methyl-1,2,4,5-tetrahydro-3H-2-benzazepin-3-one is obtained. M.P. 168°-169° C.
