Chemistry of bis-2' Cyanoethyl Derivatives of some Aromatic Amines: Part V. Preparation of some new Tertiary Amino Benzaldehydes and a study of some of their Reactions

4 NN-bis-2'-cyanoethylamino 2-ethoxy and 2 : 6-dimethylamino benzaldehydes have been prepared for the first time. Some of the reactions of these aldehydes and also of 4-NN-bis-2'-cyanoethylamino 2-rnethoxy and 2-methyl benzaldehydes have been studied. p-N-methyl-N-2'-cyanoethylamino benzalde­hyde which has so far been known through some of its derivatives has now been isolated in the pure form
