Versuchsvorschrift
To a solution of Intermediate 147(c) of Example 147 (1.5 g, 5 mmol) in CHCl3 (10 mL) and N,N-dimethylformamide (15 mL), was added N-chlorosuccinimide (701 mg, 5.25 mmol). The mixture was heated to 60° C. and stirred for 3 hours. Chloroform, N,N-dimethylformamide and water were added. Following extractive work-up with chloroform, the organic layer was dried over Na2SO4 and filtered. Evaporation of the volatile components gave a deep brown residue to which methanol was added. Filtration and collection of the solids gave the title compound (648 mg) as deep brown solid whose purity by NMR and HPLC was estimated to be about 70%.
