实验过程

A solution of 1.0 mmol of this amide, 4.0 mmol of TMSN3, 4.0 mmol of PPh3, and 4.0 mmol of DEAD in 4 mL of THF at 0° C. was stirred 24 h and then concentrated. The residue was mixed with 5 mL of THF and 12.0 mmol of 1N NaOH. After stirring for 24 h and processing by extraction, 5-(3'-bromo-4'-methylphenyl)tetrazole was obtained.
