In analogy to the procedure described in example 57c, the 4-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-methylsulfanyl-6-(2,2,2-trifluoro-ethoxy)-pyrimidine-5-carbonitrile was oxidized by 3-chloro-perbenzoic acid to 4-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-methanesulfonyl-6-(2,2,2-trifluoro-ethoxy)-pyrimidine-5-carbonitrile which was then treated with 3-picolylamine in dioxane at 40° C. during 18 hours to yield the 4-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-[(pyridin-3-ylmethyl)-amino]-6-(2,2,2-trifluoro-ethoxy)-pyrimidine-5-carbonitrile as an amorphous, light brown solid; MS: [M+H]+=487.
