Procedure

To a solution of intermediate 20 (1.066 mmol) in 1,4-dioxane (4.5 ml) and a saturated solution of NaHCO3 (4.5 ml) was added intermediate 5 (0.23 g, 0.906 mmol). The resulting solution was degassed using a stream of nitrogen and to this was added Pd(PPh3)4 (0.12 mg, 0.106 mmol). The reaction was then microwaved in a sealed tube at 150° C. for 10 minutes. The resulting cooled reaction mixture was filtered through a pad of diatomaceous earth. The filtrate was diluted with EtOAc, and then it was washed with water, dried (Na2SO4) and concentrated in vacuo. The crude reaction mixture was then purified by column chromatography (silica gel; DCM to DCM/EtOAc up to 50% as eluent). The desired fractions were collected and evaporated in vacuo to yield compound 9 that was precipitated from diethylether (0.144 g, 42%).
