실험 절차

Prepared according to the procedure described in Example 1, Step 10, using [5-(4-bromo-phenyl)-3-methyl-isoxazol-4-yl]-carbamic acid tert-butyl ester and 1-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-cyclobutanecarboxylic acid ethyl ester. Additionally, (1,1′-bis(diphenylphosphino)ferrocene)-dichloropalladium(II) was used as the catalyst in place of tetrakis(triphenylphosphine)palladium(0).
