One‐pot synthesis of 2‐aminobenzothiazoles using a new reagent of [bmim]br3 in [bmim]BF4

The one‐pot direct synthesis of 2‐aminobenzothiazoles from phenyl isothiocyanate and amines using a new reagent of 1‐butyl‐3‐methylimidazolium tribromide (Bmim]Br₃) in ionic liquid 1‐butyl‐3‐methylimidazolium tetraflouoroborate (Bmim]BF₄) is described.
