Procedure
Next, to a mixture of 2-(4-methoxy-benzyl)-2H-tetrazole-5-carboxylic acid in Toluene (15 ml) at room temperature is added SOCl2 (1 ml, 13.70 mmol) and the mixture is heated at 80° C. for 3 hr. The reaction mixture is concentrated under reduced pressure to give the crude product, which is used without further purification.
Workup
- concentrationThe reaction mixture is concentrated under reduced pressure
