A new one-pot solvent-free synthesis of pyridinyl tosylates via diazotization of aminopyridines
摘要:
A new, convenient, one-pot method for the synthesis of pyridinyl tosylates is developed. The procedure involves sequential diazotization/tosylation of aminopyridines with sodium nitrite and p-toluenesulfonic acid under solvent-free conditions in a water paste at room temperature.
