7-Bromobenzothiazole

7-Bromo-benzothiazoleSodium nitrite (0.229 g, 3.3 mmol) was added to a solution of 7-bromo-benzothiazol-6-ylamine (0.380 g, 1.66 mmol, described in WO 97/31636) in sulfuric acid (10 mL) and the resulting mixture was stirred at room temperature for 20 min. Hypophosphorous acid (10 mL) was added and the mixture was heated at 50° C. overnight. The pH was adjusted to 9-10 by addition of sodium carbonate, and the crude product was removed by filtration and washed with water. Purification by prep-HPLC gave 0.265 g (75percent yield) of the title compound as a white solid: LC-MS (EI) m/z 213 (MTo 7-bromobenzo[djthiazol-6-amine (2-18, 1 g, 4.4 mmol) in H2S04 (5 ml) was added NaNO2 (605 mg, 8.8 mmol) at 0 °C and the resulting reaction mixture was stirred for 20 mm. H3P02 (5 ml) was then added at 0 °C, and the mixture was stirred for 1 h. Upon reaction completion, the mixture was washed with saturated NaHCO3, extracted with ethyl acetate (50 mL x 3), and the combined organic phases were concentrated under reduced pressure to provide intermediate 2-19 (yellow solid, 400 mg, 42percent yield). LCMS (m/z): 214 [M + HI .To a solution of bromobenzo[d]thiazol-6-amine (30 mg, 0.13mmol) was added 50percent H
