Reaction Steps

328 g (2.31 mol) of methyl iodide were added dropwise to a stirred suspension of 363 g (2.62 mol) of potassium carbonate and 354 g (1.75 mol) of 6-chloro-2-mercaptothiazolo[4,5-b]pyridine from Example 1.2 in 2.28 l of dimethylformamide at 5° C. The reaction mixture was stirred at ambient temperature for 68 h and then poured into 4.5 l of demineralized water. The precipitate was filtered, rinsed with water (2×500 ml) and then dried in vacuo at 45° C. to give 308.9 g (yield: 81%) of 6-chloro-2-(methylthio)thiazolo[4,5-b]pyridine.
