Methanesulfonyl chloride → HCID 15729206, compound

Participants

Reaction Steps

To a solution of 2-amino-5-(2-pyrimidinylthio)thiazole (1.0 g) in a pyridine (20 ml) was dropwise added methanesulfonyl chloride (0.8 ml) at 5° C. with stirring. The mixture was stirred at room temperature for 24 hours. The reaction mixture was concentrated under reduced pressure and water was added to this residue. The mixture was extracted with a mixture of tetrahydrofuran and ethyl acetate (1:1), washed with aqueous saturated sodium chloride and dried over magnesium sulfate. The solution was concentrated under reduced pressure to give solid. The solid was recrystallized from 50% ethanol to give 2-methanesulfonylamino-5-(2-pyrimidinylthio)thiazole (0.60 g, yield: 43.8%). mp: 200° C. (dec.)
