5.12 g (8.32 mmol) of Oxone were dissolved in 170 ml of water and cooled to 5° C. A solution of 1 g (4.90 mmol) of methyl 4-amino-2-(methylsulfanyl)-1,3-thiazole-5-carboxylate in 18 ml of methanol was then added dropwise, and the solution was stirred at RT for 3 h. Most of the methanol was removed, and the remainder was extracted three times with dichloromethane. The combined organic phases were dried with sodium sulfate. Following removal of the solvent and drying of the residue under high vacuum, the solid obtained (824 mg (43% of theory)) was used without further purification.
