Procedure

Compound I (13 mg, 0.027 mmol, preparation of which is outlined above in Example 12), Pd(PPh3)4 (3.5 mg, 0.003 mmol), 4-fluorophenylboronic acid (7.6 mg, 0.055 mmol) and potassium carbonate (15 mg, 0.108 mmol) were stirred in toluene (1.5 mL) and water (0.7 mL) at 120° C. under microwave irradiation (300 W) for 20 min. The reaction mixture was then poured onto brine (5 mL) and extracted with EtOAc (3×5 mL). The organic phases were combined then dried over MgSO4, filtered, and subsequently evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography eluting with hexane/EtOAc (90:10 then 85:15) to furnish II as a colourless oil (2.5 mg, 22%).
