A number of methyl 2-aryl-4-methylthiazole-5-carboxylates 3 and their derivatives were previously prepared by the condensation of methyl α-chloroacetoacetate (1) with thiobenzamides 2 (). In order to further study the potential of the arylthiazole class of compounds as antiviral agents, the preparation of methyl 4-amino-2-(4-chlorophenyl)thiazole-5-carboxylate (6) was attempted ().

Aryl thioamides undergo a very rapid condensation in the presence of methyl bromocyanoacetate to provide quantitative yields of 3,5-diaryl-1,2,4-thiadiazoles with easy work-up and a high degree of product purity. The method can be scaled up with no loss in efficiency.

The goal of the present study was to determine the scope of the reaction of aryl thioamides 2 with methyl bromocyanoacetate (4) to determine if it could constitute a general method for synthesis of 3,5-diaryl-1,2,4-thiadiazoles.

Next, a variety of commercially available aryl thioamides 2 were allowed to react with methyl bromocyanoacetate (4) at room temperature (). Among the 1,2,4-thiadiazoles reported in the chemical literature, the ortho-substituted derivatives have been more difficult to prepare and there are fewer examples of them. Therefore, in this study more attention was given to synthesis of products containing substituents in the ortho positions of the phenyl rings and six ortho substituted derivatives 5c, 5d, 5h, 5i, 5j and 5k were prepared. The reaction of o-substituted thiobenzamides 2c, 2h, 2i, 2j and 2k proceeded in quantitative yields; however, the o-trifluoromethyl derivative 5d was obtained in low yield (10%). Most of the other meta, para, and disubstituted thiobenzamide derivatives afforded the corresponding 1,2,4-thiadiazoles in essentially quantitative isolated yields of pure products regardless of differences in electronic and/or steric properties of the substituent(s). The 3- and 4-pyridyl derivatives 5t,u were obtained in moderate yields (65–69%). However, the corresponding 2-pyridyl derivative could not be obtained in any yield and the starting materials decomposed under the reaction conditions. The condensation reaction to produce 3,5-diaryl-1,2,4-thiadiazoles did not work when 2,6-disubstituted thiobenzamides were used. To date, there are no efficient methods reported for the synthesis of 3,5-bis(2,6-dichlorophenyl)-1,2,4-thiadiazole, although it has been obtained as a by-product from the reaction of thioamides with nitrous acid. Moreover, oxidation of 2,6-dichlorothiobenzamide was reported to yield the corresponding isothiocyanate. We are unaware of any efficient methods reported for preparation of 3,5-di(2-pyridyl)-1,2,4-thiadiazole or any 3,5-[(2,6-disubstituted)aryl]-1,2,4-thiadiazole, including the presently reported method. Thioacetamide was tried as an example of an aliphatic thioamide and it was unsuccessful.
