실험 절차

To a nitrogen-saturated suspension of N-triphenylmethyl-5-[4′-methylbiphenyl-2-yl]tetrazole (10 g, 20.9 mmol) in DCM was added NBS (3.7 g, 20.9 mmol) and a catalytic amount of benzoyl peroxide (60 mg, 0.2 mmol). The mixture was stirred at reflux for 15 hours. After cooling to room temperature, the precipitate was filtered and the organic solution was concentrated in vacuo. Purification by silica gel chromatography (EtOAc/hexane) gave the title compound as a white solid.
