Abstract
524,696. Amino-benzaldehydes. I. G. FARBENINDUSTRIE AKT.-GES. Feb. 3, 1939, No. 3634. Convention date, Feb. 21, 1938. [Class 2 (iii)] p-Amino benzaldehydes are manufactured from secondary N-alkylanilines, the alkyl groups of which are branched, by reacting with formyl-N-methylaniline in the presence of phosphorus oxychloride. The products are dyestuff intermediates. In examples, N-(diisopropyl-methyl) aniline, 2-dimethyl-3-o-toluidine-butane, and α-tertiary-butyl-N-ethylaniline give the corresponding p-aminobenzaldehydes.
