Ethyl Acetate → methyl 3-(1-(2-cyanoethyl)-1H-tetrazol-5-yl)benzoate

Participants

Reaction Steps

To a solution of methyl 3-((2-cyanoethyl)carbamoyl)benzoate (400 mg, 1.7 mmol) in MeCN (15 mL) at 0° C. was added NaN3 (111 mg, 1.7 mmol), and Tf20 (0.3 mL, 1.7 mmol). The mixture was stirred at rt for 16 h before aq NaHCO3 and EtOAc were added. The organic layer was separated and re-washed twice before it was collected, dried over Na2SO4, and concentrated to methyl 3-(1-(2-cyanoethyl)-1H-tetrazol-5-yl)benzoate as an oil (180 mg, 41% yield). MS found: (M+H)+=258.
