PROCEDURE

实验过程

A mixture of 2-benzyloxy-5-chloro-phenyl-boronic acid (197 mg, 0.75 mmol), 5-amino-2′-bromo-biphenyl-3-carboxylic acid methyl ester (216 mg, 0.71 mmol), potassium carbonate (828 mg, 6 mmol) and tetrakis(triphenylphosphine)palladium(0) (79 mg, 0.068 mmol) in 1:1 toluene/ethanol (8 ml) was stirred and heated at 90° C. under nitrogen for 2 hours. After cooling the mixture was diluted with diethyl ether and water and the organic phase dried (MgSO4) and evaporated to dryness. The residue was purified using Biotage with ethyl acetate/iso-hexane (1:4) to yield the title compound as a pale yellow gum. (288 mg, 89%).
