- Abstract
The article discusses the results of a study on the opening of the pyrazine ring when treated with methylamine. When under the treatment of the aqueous solution, the 1-ethyl and 1-phenyl-6-triflouroacetylpyrrolo [1,2-a] pyrazinium methyl iodides (1a,b) were converted to 6-acyl-2-methylpyrrolo[1,2-a] pyrazinones 2a,b. This rearrangement included an initial attack at the positions 1 or 3 of the salt 1a,b by the nucleophile.
