반응 단계
In analogy to Example 175, step 6, 3,3′-dichloro-4′-[3,3,3-trifluoro-2-hydroxy-2-(6-methoxy-pyridin-3-yl)-1-methyl-propyl]-biphenyl-4-carboxylic acid methyl ester (Example 178) was treated first with aqueous HCl in dioxane, followed by aqueous NaOH in tetrahydrofuran/methanol to give the title compound as a colorless solid. MS (m/e, ISP neg. ion)=484.1 [M−H+].
