A series of isomeric imidazo [1, 2-a] pyridine-2-carbamates was prepared for testing as anthelmintics. The analogues were synthesized by reacting the appropriate 2-aminopyridine and methyl chloroacetylcarbamate. Steric hindrance in the 2, 6-disubstituted derivative resulted in the formation of the isomeric 3-substituted analogue as the major product. Carbn- 13 Nh4R proved useful in the structural assignments in this series. None of the analogues ...
