Abstract
Improvements introduced in the Main Patent or 232,318 by "Process for obtaining new amides of α -amino- β -oxicarboxylic acids", characterized in that the compounds of the general formula ** (See formula) ** where R represents an alkyl residue with at most 4 carbon atoms or a phenyl residue, R1 a hydrogen atom or an alkyl residue with at most 4 carbon atoms, and a phenyl radical optionally substituted by a low-weight carbalkoxy group molecular, where R1 and R2 may also represent, in common with the combined nitrogen atom, elements of a saturated heterocyclic system, are treated with nitrous acid.
