ABSTRACT OF THE DISCLOSURE The invention relates to a novel process and novel intermediates useful in the preparation of sympathomimetic amines. The pharmacologically useful final products, which are acyl derivatives of mono- and dihydroxy aromatic amines (e.g., catechol amines) can be prepared in optically active or racemic form by reacting the corresponding mono- or dihydroxy aromatic amine with a reagent capable of forming the N-tert-butoxycarbonyl derivative thereof; reacting the novel intermediate thus obtained with an acyloxymethyl chloride to afford the corresponding novel mono- or diacylated N-protected aromatic amine; and removing the N-protecting group therefrom.
