Versuchsvorschrift

(RS)-1-[2-(5,6-Difluoro-1H-benzoimidazol-2-ylmethyl)-piperidin-1-yl]-1-[5-(4-fluoro-phenyl)-2-methyl-thiazol-4-yl]-methanone, E35 (150 mg, 0.32 mmol) was added slowly to an ice-cooled slurry of sodium hydride (26 mg, 0.64 mmol, 60% dispersion in mineral oil) in DMF (10 ml). After stirring for a further 0.5 h, 1-iodopropane (60 mg, 0.35 mmol) was added. The mixture was stirred at room temperature for 16 h then partitioned between water and ethyl acetate. The organic phase was washed with water, brine, dried (Na2SO4) and the solvent removed in vacuo. Chromatography (silica gel, 50-100% ethyl acetate-pentane then 0-5% methanol-ethyl acetate) afforded the title compound as a white solid.
