A process for preparing 4-aminodiphenylamine using nitrobenzene and aniline as raw materials, a complex base catalyst as the condensation catalyst, and a powdery composite catalyst as the hydrogenation catalyst. The process has 5 process stages including condensation, hydrogenation, separation I, separation II, and refining.
The invention is directed to certain novel compounds. Specifically, the invention is directed to compounds according to formula (I):
and salts thereof.
The compounds of the invention are inhibitors of kinase activity, in particular IKK2 activity.
A process for preparing 4-aminodiphenylamine having the steps of reacting nitrobenzene and aniline in the presence of a complex base catalyst, hydrogenating the reaction mixture with hydrogen, a powdery composite catalyst, and a hydrogenation solvent; separating, recovering, and reusing the complex base catalyst and the powdery composite catalyst from the reaction mixture; separating, recovering, and reusing aniline, and optionally water, from the reaction mixture; refining the reaction mixture to obtain 4-aminodiphenylamine. The complex base catalyst comprises tetraalkyl ammonium hydroxide, and tetraalkyl ammonium salt.
