Procedure
In 7.4 ml of tetrahydrofuran was dissolved 160 mg of 2-chloro-5-nitro-1,3-benzothiazole, and thereto was added 1.86 ml of a 1M dimethylamine tetrahydrofuran solution, followed by 16.5 hours of stirring. Water was added to the reaction solution and the organic layer was extracted with ethyl acetate. After the organic layer was dried over anhydrous sodium sulfate, the solvent was removed by evaporation. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate) to obtain 173 mg of N,N-dimethyl-5-nitro-1,3-benzothiazol-2-amine as a yellow solid.
