Abstract
Procedure for obtaining amino ketones, of general formula: **(See formula)** in which R1 is chosen from the remains: **(See formula)** wherein R4 is chosen from a lower alkyl moiety and a benzyl moiety and R5 is selected from a hydrogen atom, a lower alkyl moiety and a benzyl moiety; R2 is chosen from a hydrogen atom and a methyl residue; R3 is chosen from hydrogen and a lower alkyl moiety and X means an alkyl moiety with a maximum of 6 carbon atoms, respectively, in the case that the R2 and R3 moieties mean hydrogen, they are defined as the grouping: **(See formula)** in which n means an integer from 2 - 12 and R1 has the above meaning, respectively, of its salts, by condensation of aminonitriles with phenols, respectively their ethers, in the presence of aluminum chloride and halogenated hydracids, in a usual solvent for the Friedel-Crafts reactions, characterized in that the aminonitriles of general formula: **(See formula)** Where R2 and R3 have the definition above and X'means an alkyl moiety with a maximum of 6 carbon atoms, respectively, in the case that the R2 and R3 moieties signify hydrogen, the group - (CH2) n-NH -CH2-CN, in which n has the definition above, respectively its salts, are reacted with phenols, respectively their ethers, of general formula: R1H (III) wherein R1 has the definition above, at temperatures below 40ºC, preferably at most 30ºC, the imino compounds of general formula being released into the reaction mixture, by addition of lower aliphatic alcohols: **(See formula)** Where R1, R2 and R3 have the definition above and X'' means an alkyl moiety with a maximum of 6 carbon atoms, respectively, in the event that R2 and R3 signify hydrogen, the group: **(See formula)** respectively their salts, and these, if appropriate after isolation with water or aqueous alcohols, are hydrolyzed to the amino ketones of formula I and, if appropriate, the salts are subsequently released.
