Process for preparing n-(3-amino-4-chlorophenyl) acylamides |
| abstract |
The present invention provides a process for preparing N-(3-amino-4-chlorophenyl) acylamides of Formula (I): comprising reacting, in a solvent comprising at least one polar solvent, in the presence of at least one acid acceptor, 1-chloro-2,4-diaminobenzene with at least one acyl chloride of formula (II): Cl-X-R wherein X is -CO- or -SO2-; R is selected from the group C1-C25 alkyl; C1-C25 alkyl substituted with one or more groups selected from C1-C12 alkoxy, aryl, aryloxy and C5-C7 cycloalkyl; aryl; C5-C7 cycloalkyl. The present invention further comprises the step of purifying said N-(3-amino-4-chlorophenyl) acylamides by crystallizing from a non-polar solvent or conducting the reaction in a mixture of at least one polar and at least one non-polar solvent. |
