Abstract
There is provided a new compound: d-N-(2-amino-2-phenethyl-2-methoxyethylamine useful in the direct synthesis of levamisole. The compound is prepared by slurrying the racemic N-(2-amino-2-phenethyl)-2-methoxyethylamine with dibenzoyl-d-tartaric acid as the resolving agent in an aqueous acidic menstruum containing ammonium chloride, heating the resultant mixture, preferably under reflux, cooling and filtering the resultant mixture to recover crystals rich in the desired d-amine compound, hereinabove noted.
