실험 절차
A mixture of 2-(6-formamidopyridin-2-yl)-2-methoxyiminoacetic acid (syn isomer) (5.0 g.) and concentrated hydrochloric acid (2.34 g.) in methanol (50 ml.) was stirred for 40 minutes at ambient temperature. After the removal of methanol from the reaction mixture under reduced pressure, the residue was pulverized in diethyl ether, collected by filtration and then dried to give a pale brown powder of 2-(6-aminopyridin-2-yl)-2-methoxyiminoacetic acid hydrochloride (syn isomer) (5.2 g.)
