In analogy to the procedure described in example 20A], (4-hydroxy-2-methyl-phenylsulfanyl)-acetic acid tert-butyl ester (example 20C]), was reacted with 3-chloromethyl-2-methyl-6-(4-trifluoromethyl-phenyl)-pyridine (example 1N]) to give {2-methyl-4-[2-methyl-6-(4-trifluoromethyl-phenyl)-pyridin-3-ylmethoxy]-phenylsulfanyl}-acetic acid tert-butyl ester, which was subsequently saponified in analogy to the procedure described in example 20B] to yield the title compound as white solid of mp. 168–169° C.
