실험 절차

To a solution of yield 3-bromo-4-(bromomethyl)benzoic acid (1.0 equiv.) in Water (0.56 M) at 95° C. was added potassium carbonate K2CO3 (5.0 equiv.). The homogenous reaction mixture was stirred at 95° C. in an oil bath for 1 hr. The reaction mixture was COOLED OFF TO RT, neutralized with 6 M HCl. diluted with EtOAc and washed with brine. The organic layer was dried over Na2SO4, filtered and concentrated. The crude was used in next step. LC/MS (m/z)=294.8 (MH+), Rt=0.80 min.
