HCID 469406363-{3-Chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(5-methyl-pyrazin-2-yl)-propyl]-phenoxymethyl}-benzoic acid methyl ester

Procedure

In analogy to Example 1, step 7, 3-chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(5-methyl-pyrazin-2-yl)-propyl]-phenol (Example 1, step 6) was reacted with methyl 3-(bromomethyl)benzoate and potassium carbonate to give the title compound as a colorless viscous oil. MS (m/e, ISP neg. ion)=492.6 [M−H−].
