Procedure
A suspension of 6-bromo-benzothiazol-2-ylamine (5 g, 21.83 mmol) in DCM (250 ml) is treated with CDI (3.54 g, 21.83 mmol) and the reaction mixture is heated to reflux for 2 hours. The reaction mixture is filtered and the resulting solid is dried in the vacuum oven overnight to afford the title compound.
