Abstract
A method of preparing imidazopyridinecarbamates of the formula: **(See formula)** where R1 is lower alkyl and R2 is hydrogen or lower alkyl; and the salts of mineral and organic acids of said compounds whose process includes the steps of: a) reacting a 2-methyl-2-thiopseudourea salt with a lower alkyl chloroformate thereby forming the corresponding intermediate lower alkyl derivative, b) reacting the lower alkyl intermediate of step a) with the desired 2,3-diaminopyridine or 2,3-diaminopyridine substituted with lower alkyl thereby forming the corresponding imidazopyridinecarbamate of Formula I.
