Prepared according to the method described in Example 12b) from (1S,2R)-4-(2-hydroxy-1-methyl-4-pyridin-3-ylbutoxy)benzeneboronic acid (0.150 g, Example 33), 2-bromo(trifluoromethyloxy)benzene (0.26 g), 2M aqueous sodium carbonate (0.50 ml) and tetrakis(triphenylphosphine)palladium (0) (0.025 g) in ethanol (3 ml). The reaction mixture was heated in a sealed vial at 80° C. for 2 hours. After cooling, the solution was is concentrated under reduced pressure and taken up in acetone and filtered through a small plug of silica. The filtrate was concentrated under reduced pressure, dissolved in dichloromethane, filtered and purified by normal-phase HPLC eluting with a gradient of 0-25% ethanol in dichloromethane to give an oil (0.145 g).
