2-Amino-6-nitrobenzothiazole → 2,6-Benzothiazolediamine

Participants

Reaction Steps

2-Amino-6-nitrobenzothiazole (1.0 g, 5.12 mmol) was dissolved in 100 ml of MeOH and palladium on activated carbon (10%, 545 mg, 0.51 mmol) was added. The reaction mixture was hydrogenated using hydrogen at RT (3 bar H2) for 2.5 h. The mixture was filtered, the solvent was removed under reduced pressure and the residue was purified using silica gel chromatography (ethyl acetate:n-heptane 1:2). 0.81 g (yield: 96%) of the purified title compound was obtained.
