Participants

Reaction Steps

A mixture of Example 319 (930 mg, 3.0 mmol), 3-thienylboronic acid (384 mg, 3.0 mmol), tetrakis(triphenylphosphine)palladium(0) (240 mg, 0.21 mmol) and sodium bicarbonate (630 mg, 7.5 mmol) in 1,2-dimethoxyethane (18 mL) and water (6 mL) was stirred under nitrogen in a heavy walled process vial in a microwave synthesizer at about 160° C. for about 10 minutes. The mixture was concentrated under vacuum and the residue was purified by flash chromatography on silica gel using hexane/ethyl acetate (3:1) as eluent to provide 240 mg (30%) of the desired product. MS (ESI): m/z 267 (M+H)+.
