Procedure
Methyl iodide (113.5 g, 0.80 mol) was added to a stirred solution of [4-(tert-butyl-dimethyl-silanyloxy)-piperidin-1-yl]-imidazol-1-yl-methanone (61.9 g, 0.20 mol) in acetonitrile (400 mL). After stirring overnight at room temperature the solvent was evaporated in vacuo. The residue was washed with ethyl acetate:heptane and dried in a vacuum oven at 45° C., yielding the title compound (60.92 g, 68% yield over three steps) as a white solid
