Yield: 97%

Reaction Conditions:

with sodium hydroxide in methanol;water at 60; for 2 h;

Steps:

2-(Benzyloxy)-5-bromobenzoic acid (10b)
To a solution of 10a (18 g, 45.3 mmol) in methanol (50 mL) was added a solution of sodium hydroxide (7.25 g, 181 mmol) in water (20.00 mL). The mixture was heated to 60 °C for 2 hrs. Solvent was removed and the residue was diluted with water, and then washed with EA. The aqueous layer was acidified with 4N HCl solution to pH=3, then extracted with EA. The organic phase was washed with water and brine, dried over Na2SO4 and concentrated in vacuum to give the title compound (13.46 g, 97 % yield). LCMS: 307, 309 [M+H]+.
