Reaction Conditions:
with water;lithium hydroxide in tetrahydrofuran at 60; for 16 h;
Steps:
25.1 Step 1 : 3-bromo-2-methylbenzoic acid.
A mixture of methyl 3-bromo-2-methylbenzoate (35.0 g, 152.79 mmol) and LiOH (10.9 g, 453.79 mmol) in THF (300 mL) and H2O (50 mL) was stirred at 60 °C for 16 h and then concentrated under vacuum. The residue was diluted with water (80 mL) and the mixture was then acidified to pH 4 with 2N HC1. The precipitated solids were collected by filtration and washed with water. The solids were dried under vacuum to afford 3-bromo-2-methylbenzoic acid (30 g, 91percent) as a white solid. MS (ESI) calculated for (C8H7Br02) [M+H]+, 214., 9, 216.9; found, 215.0, 217.0. [0676] Step 2: 3-bromophthalic acid.
