l-Ethyl-l-methyl-lp-nitrobenzylamine-2-acetimide has been prepared in crystalline form and resolved through its salt with L-dibenzoyltartaric acid. Other asymmetrically substituted aminimides derived from a series of 1-ethyl-1-methyl-1-n-butyl-2-acylhydrazonium salts in which the acyl group was acetyl, 3, 5-dinitrobenzoyl, and p-nitrophenylacetyl also were prepared, but could not be obtained crystalline. Prior resolution of one of these, l-ethyl-l- ...
