In analogy to the procedures described in example 101A], 2-(4-hydroxy-2-methyl-phenoxy)-2-methyl-propionic acid ethyl ester (described in WO 02/092590) was reacted with 5-chloromethyl-4-cyclopropyl-2-(6-trifluoromethyl-pyridin-3-yl)-pyrimidine (prepared from methyl 3-cyclopropyl-3-oxopropanoate and 4-(trifluoromethyl)benzamidine hydrochloride, in analogy to the procedures described in examples 101C] to 101F]) to give 2-{4-[4-cyclopropyl-2-(6-trifluoromethyl-pyridin-3-yl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid ethyl ester, which was subsequently saponified in analogy to the procedure described in example 101B] to yield the title compound as off-white crystalls of mp. 185.0–185.5° C.
