Reaction Conditions

Temperature	80 °C

Reaction Steps

NBS (14.60 g) and AIBN (2.89 g) were added to a solution of the product from step (i) (9.85 g) in EtOAc (200 mL). The resulting mixture was stirred at 80° C. for 20 h. After cooling the mixture was washed with sat. sodium thiosulphate, brine, dried, filtered and the solvent removed. The crude product was purified using chromatography, to give the subtitle compound, 5.30 g.
