실험 절차
200 mg (865 μmol) of the compound from Example 5A were introduced into 10 ml of tetrachloromethane, 169 mg (951 μmol) of N-bromosuccinimide were added, and the mixture was heated under reflux while irradiating with a sun lamp for 4 h. The residue after concentration was purified by flash chromatography (mobile phase: cyclohexane/ethyl acetate gradient) to result in 168 mg (63% of theory) of the title compound.
