実験手順

To a mixture of sodium 6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridine-2-carboxylate (12.7 g), benzyl hydrazinecarboxylate (9.10 g) and HOBt (7.4 g) in DMF (250 mL) was added WSC (8.50 g) at 0° C., and the mixture was stirred at 0° C. for 1 hr. Saturated aqueous sodium hydrogen carbonate solution (200 mL), water (400 mL) and saturated brine solution (200 mL) were added to the reaction mixture at 0° C., and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous' magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was washed with ethyl acetate and dried to give the title compound (14.6 g).
