실험 절차

(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 (300 mg, 0.64 mmol) was added slowly to an ice-cooled slurry of sodium hydride (51 mg, 1.3 mmol, 60% dispersion in mineral oil) in DMF (10 ml). After stirring for 0.5 h 1-bromo-2-methoxy-ethane (139 mg, 10 mmol), N,N-diisopropylethylamine (0.3 ml) and potassium iodide (5 mg) was added. The mixture was stirred at room temperature for 0.5 h then 100° C. for 16 h. The volatiles were removed in vacuo from the cooled reaction mixture. The residue was partitioned between ethyl acetate and water. The aqueous phase was extracted with ethyl acetate (2×). The combined organics were dried (Na2SO4) and the solvent removed in vacuo. The residue was triturated with ethyl acetate to afford the title compound as a solid (306 mg, 65%). Mass spectrum (Electrospray LC/MS) Found 529 (MH+). C27H27F3N4O2S requires 528. The product was dissolved in methanol and treated with 1M HCl in diethyl ether (excess). The volatiles were removed in vacuo and the residue triturated with methanol-ethyl acetate to afford the hydrochloride salt of the title compound as a white solid (66 mg).
