| titleOfInvention | PROCEDURE FOR THE PREPARATION OF AROMATIC COMPOUNDS. |
| abstract | Procedure for the preparation of aromatic compounds of the general formula **(See formula)** where B represents an alkylene chain of 2 to 4 carbon atoms, in which one or more of the hydrogens can be substituted by lower alkyl; R, R2, R3 and R4 each individually represent hydrogen, halogen, lower alkyl, lower alkoxy, hydroxyl or trifluoromethyl; and R8 represents hydrogen, hydroxy or lower alkoxy, of the tautomers of these compounds in which R8 represents hydroxyl and of the acid addition salts of all the preceding compounds, characterized in that a compound of the formula is treated **(See formula)** where R1, R2, R2 and R4 have the same meaning as before, with a diamine of the formula H2N-B-NH2 XII where B has the same meaning as before; or by cycling a compound of the formula **(See formula)** where B, R1, R2, R2 and R4 have the same meaning as before, by treatment with a Lewis acid; or because it is a compound of the formula **(See formula)** with a phenyl-organometallic derivative of the formula where R'3 and R'4 represent hydrogen, halogen, lower alkyl, lower alkoxy or trifluoromethyl, while Z is Li, MgBr, Mgj or MgC1; or because it is a compound of the formula **(See formula)** where B, R1, R2, R3 and R4 have the same meaning as before, with an oxidizing agent; oxidize, if desired, a resulting compound of formula I, wherein R8 represents hydrogen by converting it into a respective hydroxy-substituted compound, undergo lower alkylation, if desired, a resulting compound of formula I, wherein R8 represents hydroxyl, converting it into a respective compound substituted by lower alkoxy, separating itself into its antipodes optically; actives, if desired, a racemic mixture obtained and converted, if desired, a resulting base into an acid addition salt.
