The brown mixture was heated to reflux and maintained until reaction completion by HPLC. The reaction was cooled to ambient and the ethanol removed by vacuum distillation. 2- methyltetrahydrofuran (30 ml) was then added and the biphasic mixture filtered over arbocel.(TM)., extracted with saturated aqueous sodiumhydrogencarbonate (20 ml) and separated. The organic layer was extracted five times with 10percent w/v citric acid (20 ml), then to the combined aqueous layers was added 2-methyltetrahydrofuran (30 ml) then 5M sodium hydroxide until obtaining a pH>10. The layers were separated and the upper organic layer was concentrated to dryness in vacuo obtaining product as a beige solid 2.90 g (91percent yield).

The reaction was purged with nitrogen and heated at 80QC for 20 minutes. Three further portions of palladium tetrakis(triphenylphosphine) (0.123 g, 0.0125 mmol) and <strong>[89694-46-2]2-chloro-5-methoxyphenyl boronic acid</strong> (0.793 g, 4.25 mmol) were added at 20 minute intervals. The reaction was heated at 8O0C for 18 hours before concentrating in vacuo. The residue was taken up in ethyl acetate (20 ml) and washed with a saturated aqueous solution of brine (20 ml) before drying over Na2SO4 and concentrating in vacuo.
