Synthesis of 5-(5-R-2-furyl)thiazole derivatives by the reaction of 2-(5-R-furfuryl)thiuronium salts with acetic anhydride

2-Acetamide-4-methyl-5-(5-R-2-furyl)thiazoles were obtained by the reaction of 2-(5-R-furfuryl)thiuronium salts with acetic anhydride. The reaction intermediates — 2-(5-R-furfuryl)-1,3-diacetylthioureas — were isolated and characterized.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 557–562, April, 1990.
