Reaction Steps

4-Iodo-6-methoxy-2-(4-Methoxy-phenyl)-benzothiazole (175 mg, 0.44 mmol) [Compound of Example 1d] was suspended in boron tribromide (1M in methylene chloride, 3.5 mL) and stirred at room temp under nitrogen for 72.0 hr. Reaction was poured into aqueous hydrochloric acid (1M) and extracted with ethyl acetate. Ethyl acetate extracts were washed with: 1) hydrochloric acid (1.0M), 2) saturated brine and concentrated in vacuo. Washed solid was further purified by flash chromatography on silica affording the title compound (158 mg, 97%) as a yellow solid. MH+=370
