Results and Discussion
The reagent was easily prepared by simple condensation of 6-methyl-2-pyridinecarboxaldehyde and 4-phenylsemicarbazide. The product was obtained in good yield (90% theoritical). The mass spectrum indicates a prominant molecular ion peak M at m/z 254 (25%). The fragment peaks are observed at m/z 162(35%) and 134(100%) due to loss of CHsNH- and c=o respectively.The is followed by the loss of N2 to obtain a peak at m/z 106(50%) corresponding to ICH3CH3N-CH2r fragments.
