Product 1

HCID 666969875-Chloro-6-{3-chloro-4-[2-(4-cyano-3,5-dimethyl-phenyl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenoxy}-nicotinic acid methyl ester

Procedure

In analogy to Example 147, 4-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-2,6-dimethyl-benzonitrile (Example 141, step 5) was reacted with methyl-5,6-dichloro-nicotinate in the presence of cesium carbonate to give the title compound as a colorless solid. MS (m/e)=553.3 [M+H+].
