Procedure
A suspension of Compound 9 prepared in Example 4-(1) (1.2 g), N-bromosuccinimide (0.675 g), and α,α'-azobis-isobutyronitrile (10 mg) in carbon tetrachloride (70 ml) is refluxed under heating for 1 hour. The insoluble materials are removed by filtration and the solvent is evaporated. The residue is treated on column chromatography (silica gel/ethyl acetate) to give the title compound (0.54 g), which is recrystallized from ethyl acetate. Yield 36.4%.
