Procedure

The mixture (4.02 g) obtained in Example 36-1 in a carbon tetrachloride solution (45 ml) was added with N-bromosuccinimide (1.31 g) and 2,2′-azobisisobutyronitrile (0.121 g) and the whole was refluxed for 30 minutes. After that, the solution was cooled to room temperature and a solid component was separated by filtration. The organic layer was washed with a 1 mol/l sodium hydroxide aqueous solution and a saturated saline solution in the stated order, and dried with anhydrous magnesium sulfate. The solvent was distilled off and dried under reduced pressure, thereby obtaining a mixture (5.72 g) containing the subject compound.
