An improved procedure for the construction of benzothiazole scaffold via intramolecular cyclative cleavage of benzotriazole ring under free radical condition was successfully accomplished. The protocol utilises NaBH 4 which regenerates the active reagent n ‐Bu 3 SnH in the reaction medium and makes this method cost effective and less toxic as a substitute of expensive and toxic silanes.
