Vorschrift

A mixture of 9-methylphenanthrene (14.2 g, 74 mmol), benzoyl peroxide (40 mg, 0.16 mmol) and NBS (13.3 g, 74.6 mmol) in 210 mL of benzene was refluxed for 5 h. The reaction mixture was cooled to 0° C. and the succinimide precipitated was removed by filtration. The filtrate was washed by 15% NaOH, dried over MgSO4 and concentrated to yield 18 g of product which was used for the next step without further purification.
