Abstract
Phenyl-4-heteroarylaminomethylene-5(4H)-oxazolones 3, which were prepa red from the corresponding N,N-dimethyl-N'-heteroarylformamidines 1 an d hippuric acid 2 in acetic anhydride, react with amino acids giving d ehydropeptide derivatives 4, 5, and 6 as products. Dehydration of N-pr otected peptides 7-10, containing glycine at the C-terminal, followed by the reaction with formamidines 1 gave ituted-4-heteroarylaminomethy lene-5(4H)-oxazolones 11-14.
