Reaction Steps

To a solution of 6-hydroxy-2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophen-3-yl 3-bromo-4-[(1-pyrrolidinyl)methyl]phenyl ketone (Example 137, Part D) (81 mg, 0.13 mmol) in DMF (2 mL) in a pressure tube were added tetrakis(triphenylphosphine)palladium(0) (18 mg) and tetramethyltin (0.3 mL) sequentially, followed by flushing with argon. The mixture was allowed to stir in the sealed pressure tube at 135° C. for 23 h in dark. The cooled reaction mixture was fractionated directly through flash chromatography with Et3N:MeOH:EtOAc (5:10:85) to afford the title compound (32 mg, 44%).
