Reaction Conditions:

with thionyl chloride at 0 - 80; for 1 h;

Steps:

40.1
Step 1. Methyl 3-methyl-4-nitrobenzoate To a solution of 3-methyl-4-nitrobenzoic acid (30 g, 165.61 mmol) in methanol (300 mL), was added thionyl chloride (25 mL) dropwise with stirring at 0° C. After stirring for 1 h at 80° C., the resulting mixture was concentrated under vacuum to give residue, which was dissolved in petroleum ether (100 mL) and filtrated to give methyl 3-methyl-4-nitrobenzoate as a white solid (31 g, 96%). LC/MS (ES, m/z): [M+H]+ 196.0 1H-NMR (300 MHz, CD3Cl) δ 7.99-8.04 (m, 3H), 3.98 (s, 3H), 2.64 (s, 3H)
