Reaction Steps

In analogy to Example 26, step 4, 3-chloro-4-[2-(2-chloro-pyridin-4-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-benzoic acid (Example 26, step 3) was reacted with beta-alanin-methyl ester hydrochloride and HBTU at 80° C. 2 h to give the title compound as a colorless viscous oil. MS (m/e, ISP neg. ion)=477.0 [M−H+].
