Reaction Conditions:
with lithium hydroxide monohydrate;sodium hydroxide in methanol at 20; for 15 h;
Steps:
Step C. Intermediate 114: 5-Bromo-4-fluoro-2-methoxybenzoic ac
A solution of NaOH (16.88 g, 421.95 mmol) in H2O (80 mL) was added slowly to a stirred solution of Intermediate 113 (37 g, 140.6 mmol) in MeOH (250 mL) at 20 °C. The resulting solution was stirred at 20 °C for 15 h. The reaction mixture was poured into ice/H2O (2 L), extracted with DCM (3 x 500 mL), the organic layer was dried over Na2SO4, filtered and evaporated to afford the title compound (34.0 g, 97%) as a white solid.1H NMR (300 MHz, CDCl3): δ 4.09 (s, 3 H), 6.88 (d, 1 H), 8.41 (d, 1 H). (ESI): m/z [M+H]+ 249.8.
