Procedure

A mixture 5-amino-2-methyltetrazole (5.00 g, 50 mmol) and 3,5-bis(trifluoromethyl)benzaldehyde (19.5 g, 81 mmol) in toluene (100 mL) is stirred and refluxed for 3 hours. The resulting mixture is concentrated to give crude 2-methyl-N-[3,5-bis(trifluoromethyl)phenylmethylene]-2H-tetrazole-5-amine.

Workup

  1. temperaturerefluxed for 3 hours
  2. concentrationThe resulting mixture is concentrated
