실험 절차
9.2 g (1-trityl-1H-imidazol-4-yl)-acetonitrile are dissolved in 120 mL THF, the solution is cooled to −5° C. and 1.8 mL methyl iodide and 1.08 g sodium hydride (60%) are added. The suspension is stirred for 12 h at RT and then applied directly to RP gel and purified by RP chromatography (C18, 10/90 to 90/10 acetonitrile/water in 15 min-0.2% formic acid is added to both solvents).
