B. P. Asthan; P. I. Ittyerah

2-Methyl-4-NN-dimethylaminobenzaldehyde was prepared by formylating 2-methyl-4-NN-dimethylaniline ming dimethyl form:1mide and its identity established by the preparation of its oxime, 2 :4 DNP, semiacarbazone, azine etc. and also by studying its I. R. spectrum. The aldehyde has been condensed with cyanacetamide, ethylcyanacetate, malono-nitrile, rhodamne, nitromethane, hydantoin, thio-hydantoin, iso-nicotinic acid hydrazide and the products isolated and identified. The aldehyde has also been condensed with benzoyl, cinnamoyl, anisoyl, o-and p-chlorobenzoyl and m- and p-nitrobenzoyl glycines and the corresponding 5(4) oxazolones obtained.

Preliminary experiments show that the aldehyde can be used as a reagent for the chromatographic detection of acyl glycines and the rhodanine derivative as a reagent for detection of certain metals.
