Synthesis of thiophene-based TAK-779 analogues by C-H arylation

A rapid synthesis of thiophene-based TAK-779 analogues 1 is reported using a late-stage diversification strategy. At the end of the synthesis, the key building block 2, which was prepared in six steps from thiophene, was arylated regioselectively at the α
