Abstract

A process for preparing N-acylated 2-aminobenzophenone derivatives of the general formula i ** (see formula) ** Wherein r represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; x represents a hydrogen atom, a halogen atom, a nitro group or a trifluoromethyl group; y represents a protective group that can be eliminated by means of treatment with acids or by hydrogenation; r'represents a hydrogen atom or a group that appears in natural alpha-amino acids as the side chain attached to the carbon atom in the alpha position; which comprises preparing, by methods known per se, a protected amino acid chloride of the general formula iii ** (see formula) ** Wherein y and r'have the same meanings as above from the corresponding protected amino acid, and then add to the reaction mixture a benzophenone derivative of the general formula ii ** (see formula) ** Wherein x and r have the same meanings as above, and carry out the acylation reaction in the absence of acid-binding agents.
