Procedure

A mixture of N-triphenylmethyl 5-(4'-methylbiphenyl-2-yl)tetrazole (Example 11, 12.7 g), N-bromosuccinimide (4.6 g), carbon tetrachloride (300 mL), and benzoyl peroxide (75 mg) was heated at reflux for 2.5 hours. The cooled suspension was filtered and the filtrate was evaporated to give the title compound as a crystalline solid. 1H-NMR (CDCl3) δ 8.2 6.7 (complex, 23H), 4.3 (s, 2H).
