Abstract
4,5-Disubstituted 2-mercaptoimidazoles react with chloroacetic acid to form S-carboxy-methyl derivatives, which readily cyclise to the corresponding 2,3-dihydro-imidazo[2,1-b]-thiazol-3-ones. Substituted amides of 2-imidazolylthioacetic acids have now been obtained by the action of amines on the latter compounds. The 2-arylidene and 2-arylazo derivatives of 2,3-dihydroimidazo[2,1-b]thiazol-3-ones are prepared. The action of GRIGNARD reagents on the 2-arylidene derivatives results in addition to the exocylic double bond.
