Procedure

Methyl iodide (0.035 mL, 0.57 mmol) was added to a stirred suspension of 8-Methoxy-5-methyl-2-[2-(2-phenyl-1H-imidazol-4-yl)-ethyl]-[1,2,4]triazolo[1,5-a]pyridine (145 mg, 0.435 mmol) and Cs2CO3 (360 mg, 1.1 mmol) in 2-Butanone (10 mL). The mixture was heated at 50° C. for 7 hours under an atmosphere of Argon. The mixture was cooled to rt and the solvent was evaporated off. The crude product was dissolved in DCM and purified by silica gel chromatography (Eluent: 0-100% EtOAc in n-heptane, then changed to 0-5% MeOH in EtOAc). Yield: 31 mg (20%) of the title compound as an off white solid. LC-MS: m/z=348.2 (MH+), tR=0.70 min, method E.
