Introduction A serles of 5, 5-dlmethyi-2-lhlazollne-4-carboxylates wlth a phenyl or methyl group at the 2-podtlon of the rlng were prepared from the correspondlng methyl or ethyl ester of penklllamlne and elther methyl benzlmldate or ethyl acetlmidate. The free acld was obtained by the reactlon of penlclllamlne wlth benzonltrlle to produce 5, 5-dlmethyl-2-phenyl- 2-thlasollne-4-carboxyllc acld. Correspondlng thiazollnes were prepared from cystelne In ...
