Bucharaine, with mp 151-152" C (from methanol) has the composition C19H2sOaN 4, mol. wt. 331 (mass spectrometry). It gives a dibromo derivative with mp 145-146 ° C (from acetone), an O-acetyl derivative with mp 168-169" C (from acetone), and a N-methyl derivative with mp 142-143" C. The IR spectrum of the alkaloid has absorption bands at 3310 c m 1 (hydroxy group), 2955 (NH group), and 1657 cm -1 (amide carbonyl). The UV spectrum has the three maxima that are characteristic for 2-quinolone… Expand
