Reaction Steps

to a solution of ethyl 7-bromoheptanoate (2.0 g, 8.43 mmol, 1 eq) in EtOH (15 mL) and H2O (10 mL) was added LiOH (2.0 g, 83.3 mmol, 10 eq). The mixture was stirred overnight at room temperature. The mixture was neutralized with 2N aqueous HCl with cooling in an ice-water bath, and the mixture was extracted with EtOAc. The EtOAc layer was separated, washed with water and brine, and dried over Na2SO4. Filtration and concentration in vacuo gave 1.7 g (96%) of the 7-Bromoheptanoic acid as a white solid.
