Abstract
Process for preparing acylaminophenol alkanols, of the general formula ** (see formula) ** In which R is hydrogen or a lower alkyl with one to four carbon atoms, And it is the acyl radical of an aliphatic, saturated or unsaturated monocarboxylic or dicarboxylic acid, of an aromatic or heterocyclic acid or of a more complex organic acid, possibly with its own physiological action (as, for example, theophylline acetic acid), R'is hydrogen or a lower alkyl group, linear or branched, with two to four carbon atoms and X and z are hydrogen or y (in which case y has the meaning stated above), Characterized by total or partial acylation of amines of the general formula ** (see formula) ** In which R and r'have the meaning stated in the formula (I) y R "is hydrogen, Or its acid addition salts, in a manner known per se, with reactive derivatives of the aforementioned carboxylic acids (such as halides, anhydrides or esters); or by partially or totally acylating the amines of the formula (II) with corresponding carboxylic acids, with the addition of water-releasing agents (such as, for example, carbonyldiimidazole or dicyclohexylcarbodiimide) or at elevated temperature.
