実験手順

Prepared according to the method described in Example 12b) from (1S,2R)-4-(2-hydroxy-1-methyl-4-pyridin-3-ylbutoxy)benzeneboronic acid (0.20 g, Example 33), 4-bromo-2-chlorobenzonitrile (0.288 g), 2M aqueous sodium carbonate (0.76 ml) and tetrakis(triphenylphosphine)palladium (0) (0.075 g) in ethanol (5 ml) with heating at 90° C. for 4 hours. After work up, the residue was purified by normal-phase HPLC eluting with a gradient of 0-10% ethanol in dichloromethane to give the title compound as an oil (0.18 g).
