    Abstract: Provided are methods for preparing a compound of Formula I: where the method comprises the steps of: contacting a compound of Formula II: with 1,3,5-benzene-tricarbonyl chloride in the presence of a polar aprotic solvent to form an amide adduct; and subsequently condensing the amide with a proximate anilino group present in the adduct in the presence of a condensing agent to form a compound of Formula I wherein R1, R2, Ar, m, p, and t are as defined in the specification.

    Abstract translation: 提供制备式I化合物的方法:其中该方法包括以下步骤:在极性非质子溶剂存在下使式II化合物与1,3,5-苯三羰基氯接触以形成酰胺加合物 ; 并随后在存在缩合剂的情况下将酰胺与存在于加合物中的邻近苯胺基缩合,以形成式I化合物,其中R 1,R 2,Ar ,m,p和t如说明书中所定义。
