2,2′-azobisisobutyronitrile (982 mg, 6 mmol) and acetonitrile (100 ml) were added to 7-methyl-2-naphthalene carbonitrile (10.0 g, 60 mmol) at room temperature. N-bromosuccinimide (10.6 g, 60 mmol) was added thereto, and the mixture was subjected to heating and refluxing for 2 hours. The resultant mixture was cooled to room temperature. Water (100 ml) and toluene (100 ml) were added to the mixture for extraction. The resultant organic layer was washed twice with water (100 ml). After concentration of the organic layer under reduced pressure, the residue was subjected to silica-gel-column chromatography to yield 11.4 g of the title compound (78% yield). The data measured by instruments agreed with the data described in J. Med. Chem., 1991, 3105.
