Reaction Steps

A mixture of the compound from Step A (77.3 g), 48% HBr (310 ml), and acetic acid (620 ml) was heated under reflux for 18 hours. The resulting mixture was cooled to room temperature and poured into 3 liters of water. The resulting solution was extracted with ethyl acetate (3×500 ml). The 200 ml), dried over Na2SO4, the solvents were removed by evaporation and the residue was dissolved in 10% HCl/methanol (500 ml). After 1 hour at room temperature the volatile components were removed by evaporation in vacuo. The resulting residue was triturated with hexane to yield the title compound, mp 115°-116°.
