The present invention relates to methods of preparing compounds of formula (I) comprising the step of reacting the corresponding amide with the corresponding substituted aryl in the presence of a catalyst, which catalyst comprises copper and a ligand, Y is CHCHR6(R7) or C=C(A)Z, CY2(R2)Y3(R3), C=N-NR4(R5); Y2 and Y3 are, independently, O, S, N; A and Z are, independently, C1-6 alkyl; R1 is CF3 or CF2H; R2 and R3 are, independently, C1-8 alkyl, wherein R2 and R3 are optionally joined to form a 5-8 membered ring; R4 and R5 are, independently, C1-8 alkyl; B is a single bond or a double bond; R6 and R7 are, independently, hydrogen or C1-6 alkyl.
本发明涉及制备式(I)化合物的方法,包括在催化剂的存在下,将相应的酰胺与相应的取代芳基反应,所述催化剂包括铜和配体,其中Y为CHCHR6(R7)或C=C(A)Z,CY2(R2)Y3(R3),C=N-NR4(R5);Y2和Y3分别为O、S、N;A和Z分别为C1-6烷基;R1为CF3或CF2H;R2和R3分别为C1-8烷基,其中R2和R3可选地连接以形成5-8成员环;R4和R5分别为C1-8烷基;B为单键或双键;R6和R7分别为氢或C1-6烷基。
