To a solution of the product of example 22 part (ii) (0.5 g) in ethanol (0.8 ml) and toluene (3 ml) was added 2M sodium carbonate solution in water (1.4 ml), phenylboronic acid (0.131 g) and tetrakis(triphenylphosphine)palladium(0) (1.2 g). The reaction was heated to reflux for 2 hours, cooled and concentrated in vacuo. The residue was purified by flash column chromatography to give the sub-title compound (0.4 g).
