The ultraviolet spectrum has been fully determined. In MeOH it shows a single broad absorption maximum at 279 mJl. In 0.1 N/HC1 there is a very small hypsochromic shift to 277 mJl while in 0.1 N/NaOH, there are two absorp_x0002_tion maxima at 279 and 319 mμ. Two methoxyl groups, two imino groups and one hydroxyl group are present. The latter furnishes the O-methy1 ether, m.p. 163°C;[α]20D - 18.8° (MeOH). The above structure has been confirmed by synthesis.
