Single-vessel process for preparing ring-substituted n-alkylanilines |
| abstract |
Process for preparing ring-substituted N-alkylanilines of the formula (1) ##STR1## in which R 1 and R 2 each denote methyl or ethyl, in a single vessel, which comprises acylating m-nitroaniline in an excess of an aliphatic carbonyl compound of the formula (2) ##STR2## in which R 1 is as defined above, with an acylating agent which contains the --CO--R 2 acyl radical--which is transferred-- and reductively alkylating the resulting compound of the formula (3) ##STR3## in which R 2 is as defined above, at temperatures of 120°-160° C. under a hydrogen pressure of 20-150 bar without intermediate isolation through the presence of an acid reaction promoter and of a nickel catalyst. |
