该中间体在本合成路线中的序号：(I)N-Boc-L-tyrosine tert-butyl ester (I) was converted to the aryl triflate (II) by means of trifluoromethanesulfonic anhydride and pyridine. Palladium-catalyzed coupling of triflate (II) with 2,6-dimethoxyphenylboronic acid (III) furnished the biphenyl compound (IV). The N-Boc protecting group of (IV) was then selectively removed by treatment with sulfuric acid in tert-butyl acetate, yielding amino ester (V).
