Microwave-promoted synthesis and fluorous purification procedures have been employed successfully to generate 4-(tetrathienyl)butyric acid rapidly. Initially, a fluorous tag 1H,1H-perfluorooctylamine was tethered to 4-(thienyl)butyric acid via an amide traceless linkage. Subsequent, sequential α-bromination and Stille cross-coupling reactions with 2-(tributylstannyl)thiophene grew the fluorous-tagged
