The present invention relates to processes for producing a diaryl amine compound of the formula (I); or a salt thereof, said process comprising the step of coupling a compound of formula (II) with an amine of formula (III) in the presence of an alkali metal salt or a transition metal catalyst, wherein: Ar1 and Ar2 are independently Q; wherein each Q is an aryl or heteroaryl ring system optionally fused to a saturated or unsaturated 5-8 membered ring having 0-4 heteroatoms; wherein Q is optionally substituted as defined in claim 1, wherein: X is a leaving group; and Y is -C(O)-O-Z; and Z is selected from C1-C6 aliphatic, benzyl, Fmoc, -SO2R’ and Q, provided that Q is not substituted with X or alkyne; wherein R’ is as defined in claim 1.
本发明涉及制备式(I)的二芳胺化合物或其盐的过程;所述过程包括在碱金属盐或过渡金属催化剂存在下,将式(II)化合物与式(III)胺偶联的步骤,其中:Ar1和Ar2独立地为Q;其中每个Q是一个芳基或杂芳基环系统,可选地与含有0-4个杂原子的饱和或不饱和的5-8成员环融合;其中Q可按权利要求1中定义进行取代;其中:X是一个离去基团;Y是-C(O)-O-Z;Z从C1-C6脂肪族、苄基、Fmoc、-SO2R’和Q中选择,前提是Q未被X或炔烃取代;其中R’如权利要求1中定义。
