Reaction Steps

6-Bromo-4-trifluoromethoxy-benzothiazol-2-ylamine (157 mg, 0.50 mg), triethylamine (0.21 ml, 1.5 mmol) and palladium on carbon (10%, 15 mg) are suspended in ethanol (12 ml) and hydrogenated at atmospheric pressure for 96 h. The catalyst was filtered off and the solution evaporated to dryness. The residue was dissolved in ethyl acetate, washed three times with water, dried and the solvent removed in vacuo. The product is obtained as brown solid (85 mg, 73%). MS: m/e=235 (M+H+).
