Procedure

Compound II (22 mg, 0.046 mmol), Pd(PPh3)4 (1.6 mg, 0.0014 mmol), phenylboronic acid (11.2 mg, 0.092 mmol) and potassium carbonate (9.5 mg, 0.07 mmol) were stirred in toluene (2 mL) at 90° C. in a sealed tube for 20 h. Then the reaction mixture was filtrated through celite and evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography eluting with hexane/EtOAc (90:10 to 70:30) to furnish 16 mg of III in mixture with the starting material. MW: 403.52. LCMS (ES). found 404.2 [MH]+.
