Reaction Steps

To a suspension of the compound [179] (7.4 mg) in methylenechloride (0.2 mL) was added 1M methylenechloride solution of borane tribromide (0.2 mL) under ice-cooling, and then the reaction mixture was stirred at 0° C. for 3 hours. The reaction mixture was quenched with water, and extracted with ethyl acetate. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by reverse phase preparative liquid chromatography to give the titled compound (3.7 mg) as a pale brown solid.
