Prepared according to the method described in Example 33a) from toluene (3 ml), aqueous sodium carbonate (2 M, 1.4 ml), ethanol (0.8 ml), 3-bromobenzamide (0.5 g), (±)-4-[4-(3-pyridyl)-2-(tert-butyldimethylsilyloxy)butoxy]benzeneboronic acid (1.0 g) and tetrakis(triphenylphosphine)palladium(0) (70 mg) with heating at 120° C. for 3 hours. The residue obtained after work up was purified by column chromatography over silica eluting with 5% ethanol in dichloromethane to give a yellow gum which was deprotected as in Example 34e) using hydrofluoric acid (40%, 5 ml, CAUTION) in acetonitrile (20 ml). The residue obtained after work up was triturated with diethyl ether to give the title compound as a pale yellow solid (0.224 g)
