In analogy to the procedures described for intermediate 1 and for intermediate 4 B), 4,6-dimethyl-2-(3-trifluoromethyl-phenyl)-pyrimidine-5-carboxylic acid (intermediate 5) was converted into its acid chloride and subsequently reacted with benzoic acid (S)-1-piperidin-4-yl-pyrrolidin-2-ylmethyl ester (intermediate 3) to give benzoic acid (S)-1-{1-[4,6-dimethyl-2-(3-trifluoromethyl-phenyl)-pyrimidine-5-carbonyl]-piperidin-4-yl}-pyrrolidin-2-ylmethyl ester, which was subsequently saponified to give the title compound as colorless solid. MS: 463.2 (MH+).
