Reaction Steps

A solution of 2-bromo-5-chloro-3-methylbenzthiophene (5 g, 19.1 mmol), vinyltributylstannane (5.59 mL, 19.1 mmol), Pd2dba3 (525 mg, 0.57 mmol), and tri(2-furyl)phosphine (532 mg, 2.29 mmol) in NMP (70 mL) at 90° C. was stirred for 18 hours and concentrated. The concentrate was purified by flash column chromatography on silica gel with hexanes to provide the desired product. MS (ESI(−)) m/e 207 (M−H)−.
