실험 절차

Prepared according to the method described in Example 12b) from (1S,2R)-4-(2-hydroxy-1-methyl-4-pyridin-3-ylbutoxy)benzeneboronic acid (0.15 g, Example 33), 4-bromophenylurea (0.16 g), 2M aqueous sodium carbonate (0.25 ml) and tetrakis(triphenylphosphine)palladium (0) (0.1 g) in ethanol (3 ml). The reaction mixture was heated at 100° C. for 3 hours. After cooling, the solution was concentrated under reduced pressure. The residue was triturated with acetone and then filtered through silica gel. The filtrate was concentrated under reduced pressure and purified by flash column chromatography eluting with 10% methanol in dichloromethane give the title compound as a solid (0.046 g).
