The 5-bromo-thiophene 2-carboxylic acid amide (2BW) (7 g, 34.1 mmols) was dissolved in dichloroethane (170 ml). Triethyloxonium hexafluorophosphate (10.16 g, 40.97 mmols) was added and the resulting mixture was refluxed for 1 hr at 90° C. The reaction mixture was concentrated under reduced pressure, and was taken directly to next step.
