Small heteroaromatic rings are valuable monomers in drug discovery that can enable rapid access to novel and desirable chemical space. Installation of a synthetic handle on a heteroaromatic core may be difficult if steric and electronic factors are not in alignment with the desired transformation. Described are practical routes for the construction of 5-bromo-6-methyl imidazopyrazine (1) as well as 5-bromo and 5-chloro-6-methyl imidazopyridines (2a and 2b), which were developed using electron density surface maps encoded with ionization potential to guide synthetic strategy.

This paper describes a facile separation method for a mixture of the isomeric aminomethylpyrazines by two-stage processes.Thus the mixture of aminomethylpyrazines was converted into that of the aminobromomethylpyrazines, which could be separated by chromatography on silica gel.Each of the bromopyrazines was hydrogenated to regenerate the original aminopyrazine as a pure form.
