Reaction Steps

A solution of [2-bromo-4-(1H-tetrazol-1-yl)phenyl]acetic acid (500 mg, 1.77 mmol), Boc-piperazine (329 mg, 1.77 mmol), EDC (418 mg, 2.12 mmol), HOBt (286 mg, 2.12 mmol) and TEA (530 mg, 5.31 mmol) in 20 mL of DCM was stirred at room temperature overnight. The solvent was removed under reduce pressure and the crude was purified via prep-TLC to afford tert-butyl 4-{[2-bromo-4-(1H-tetrazol-1-yl)phenyl]acetyl}piperazine-1-carboxylate.
