실험 절차

A solution of N-(6-hydroxy-pyridin-3-yl)-benzamide (214 mg, 1.00 mmol), 3-[4-(tert-butyl-dimethyl-silanyloxy)-piperidine-1-carbonyl]-1-methyl-3H-imidazol-1-ium iodide (451 mg, 1.00 mmol) and 1,4-diazabicyclo[2,2,2]octane (112 mg, 1.00 mmol) in dimethylformamide (10 mL) was stirred for 18 hours at room temperature followed by heating for 3 days at 40° C. The solvent was evaporated in vacuo and the residue was purified by flash column chromatography (SiO2, ethyl acetate:heptane 40:60), yielding the title compound (364 mg, 77% yield)
