Procedure

The product from Step b (3.35 g, 17.3 mmol) is placed in 37 ml water together with sodium hydroxide (970 mg, 24.2 mmol). Bromine (893 μl, 17.3 mmol) is added dropwise with stirring at RT. During the addition, a light brown solid precipitates. Stirring is continued overnight at RT. The precipitated solid is filtered off at the pump, washed with a little water and then dried under high vacuum. 4.25 g of the target product of adequate purity (ca. 83% by LC/MS) are obtained.
