Abstract
The generation of a carbanion from 2-methylpyrazine by phase-transfer catalysis and its autooxidation to pyrazinecarboxylic acid have been s tudied. This acid is the starting material for the effective antituber cular agent pyrazinamide. Optimum conditions were found for the synthe sis of pyrazinecarboxylic acid. Molecular oxygen, the cheapest and mos t ecological agent, was used as oxidizing agent.
