Conditions

Temperature: 110 °C

Procedure

Prepared according to the method described in Example 33a) from toluene (5 ml), aqueous sodium carbonate (2 M, 1 ml), (2R)-1-(4-bromophenoxy)-4-(3-pyridyl)-2-butanol (0.25 g), ethanol (1 ml), 4-fluorobenzeneboronic acid (0.119 g) and tetrakis(triphenylphosphine)palladium(0) (22 mg) with heating at 110° C. for 4 hours. The residue obtained after work up was purified by column chromatography over silica eluting with ethyl acetate to give the title compound as a white solid after recrystallisation from ethyl acetate:hexane (1:1) (0.18 g).
