Example 20[6-(3-Chloro-[1,2,4]triazol-1-yl)-3-methyl-5-(3-trifluoromethyl-phenyl)-pyridin-2-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone; A well stirred solution of 0.17 g (1.59 mmol) of 3-chloro-1H-[1,2,4]triazole in 1.0 ml of 1-methyl-pyrrolidin-2-one was treated at RT with 0.058 g (1.32 mmol) of a sodium hydride (55% in mineral oil). After 30 min, 0.20 g (0.44 mmol) of [6-chloro-3-methyl-5-(3-trifluoromethyl-phenyl)-pyridin-2-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone (example 3) was added and the reaction mixture was heated up to 150 C. After 24 hours, it was poured into crashed ice and extracted twice with EtOAc; the organic phases were washed with water, dried over magnesium sulfate, filtered and evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 1:0 to 95:5) to give 0.11 g (48%) of the title compound as yellow oil. MS: 519.3 (MH+, 1Cl).
