0.30 g (0.50 mmol) of [6-[1-(4-methoxy-benzyl)-1H-[1,2,3]triazol-4-yl]-3-methyl-5-(3-trifluoromethyl-phenyl)-pyridin-2-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone (intermediate 13) in 3.2 ml of trifluoroacetic acid were stirred at reflux for 23 hours. The reaction mixture was then poured into crashed ice, the pH was adjusted to 8-9 with aqueous Na2CO3 and the mixture was extracted twice with CH2Cl2; the organic phases were washed with water, dried over magnesium sulfate, filtered and evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 98:2 to 4:1) to give 0.19 g (77%) of the title compound as an off-white solid. MS: 485.4 (MH+).
