실험 절차

To a solution of 2-benzyloxymethyltetrazole (1 mmole) and TMEDA (2 mmole) in 3 mL diethyl ether at −78° C. was added n-BuLi in hexanes (1 mmole). This was let stir for 5 min at −78° C. and then it was added to a precooled (−78° C.) solution of (n-Bu)3SnCl (1 mmole) in 2 mL of diethyl ether. After stirring at −78° C. for 30 min it was diluted with water and diethyl ether. Extraction and chromatography provided 2-benzyloxymethyl-5-(tributylstannyl)tetrazole as a colorless oil.
