Sodium hydride-induced cyclization of 1-[(isocyanomethyl)sulfonyl]-4-methylbenzene or ethyl isocyanoacetate with various xanthate esters gave 5-alkoxy-4-tosylthiazoles or ethyl 5-alkoxythiazol-4-ylcarboxylates, respectively, in good to excellent yields. The xanthate ester S-methyl O-phenyl dithiocarbonate gave 5-(methylsulfanyl)-4-tosyl-1,3-thiazole when treated with 1-[(isocyanomethyl)sulfonyl]-4-methylbenzene under similar conditions.
