Reaction Steps

n-Butyl lithium (1.53 M) hexane solution (6.5 ml, 9.98 mmol) was added dropwise to a solution of 1-ethyl-5-methyl-1H-tetrazole (0.80 g, 7.13 mmol) in THF (15 ml) while stirring at −70° C., and the mixture was further stirred for 1.5 hours. A solution of 3-chloro-2-methyl-1-propene (0.77 ml, 7.84 mmol) in THF (5 ml) was added to the mixture, and the resulting mixture was stirred for 2 hours. Water was added to the reaction mixture, the resulting mixture was extracted with ethyl acetate, and the extract was dried over magnesium sulfate, and then concentrated under reduced pressure to afford 1-ethyl-5-(3-methyl-3-butenyl)-1H-tetrazole (0.95 g, yield 80%) as a brown oil.
