Pyrrolotriazines-1,2,4 III. Etude de la dioxo-1,4 tetrahydro-1,2,3,4 pyrrolotriazine-1,2,4

1,4-Dioxo-1,2,3,4-tetrahydro-1,2,4-pyrrolo-1,2,4-triazine (1) was synthesized either by cyclising the N-carbethoxyhydrazide of pyrrole-2-carboxylic acid (2) or by alkaline rearrangement of 2-(2-pyrrolyl)-5-oxadiazolone (3).The methylation reactions of the dilactam 1 were achieved with dimethyl sulfate or diazomethane and afforded mixtures of O-methylated and N-methylated derivatives which were isolated by gas chromatography and the structures of which were assigned using ir and 1H nmr spectra.
