Procedure

To a solution of 1 (229 mg, 1.00 mmol) in DME (3 mL) was added 4-methoxycarbonylphenylboronic acid (216 mg, 1.20 mmol), Pd(PPh3)4 (0.065 mg, 0.056 mmol) and 2 N Na2CO3(aq) (1.5 mL, 3.0 mmol). The reaction mixture was stirred for 2 h at 90° C. The solution was then cooled at room temperature and poured into AcOEt. The organic layer was washed with water, brine and dried (Na2SO4), filtered and concentrated to give a yellow oil. The residue was purified by silica gel column chromatography with EtOAc (15%) in Hexanes to afford 2 (327 mg, 99%) as a yellow foam. LRMS (ESI): (calc) 329.1 (found) 330.3 (MH)+.
