Versuchsvorschrift

A solution of the product from step (i) (6.05 g) in 1,2-dichloroethane (85 ml) with N-bromosuccinimide (4.1 g) was irradiated with a 500 Watt halogen lamp for 1 h. After cooling to room temperature, triethylamine (7 ml) was added with further stirring for 0.5 hours. The solvents were evaporated under reduced pressure and the residue triturated with acetone, filtered and then further washed with water and then dried under vacuum to leave the subtitle compound as a cream solid.
