Procedure

2,2′-azobisisobutyronitrile (491 mg, 3 mmol) and isobutyronitrile (50 ml) were added to 7-methyl-2-naphthalene carbonitrile (5.0 g, 30 mmol) at room temperature. N-bromosuccinimide (5.3 g, 30 mmol) was added thereto, and the mixture was heated at an internal temperature of 80° C. for 2 hours. After that, the experiment was conducted in the same way as Example 12. Analysis by reversed-phase chromatography by use of the obtained product from Example 11 as a standard sample revealed that 4.3 g of the title compound was obtained (58% yield).
