A solution of the product of Step A (2.1 g) in ether (11 mL) was treated with bromine (0.53 mL) and the mixture stirred for 26 hours. The mixture was poured into saturated sodium bicarbonate solution (50 mL) and the organic layer was separated. The aqueous layer was washed with a fresh portion of ether (50 mL) and the combined organic layers were washed with brine (50 mL), dried over magnesium sulfate, filtered, and evaporated to yield the title compound (2.8 g).
