The present invention provides an efficient process for the production of N-acylaniline derivatives by selectively alkylating an amide group at the nitrogen atom. The process comprises reacting an amide compound of the formula (2): (wherein, R1 and R2 are each independently an alkyl group, a substituted alkyl group, an alkenyl group, a substituted alkenyl group, an aryl group or a substituted aryl group) with a sulfuric acid ester in the presence of a solid metal hydroxide to give an N-alkylamide compound of the formula (3): (wherein R3 is an alkyl group and R1 and R2 have each the same meaning as described above).
The present invention provides 2,4-pyrimidinediamine compounds that inhibit the IgE and/or IgG receptor signaling cascades that lead to the release of chemical mediators, intermediates and methods of synthesizing the compounds and methods of using the compounds in a variety of contexts, including in the treatment and prevention of diseases characterized by, caused by or associated with the release of chemical mediators via degranulation and other processes effected by activation of the IgE and/or IgG receptor signaling cascades.
