Reaction Steps
To a solution of 2,3-dimethoxybenzoic acid (10.9781 mmol, 2.0 g) in CH2Cl2 (20 mL) with a drop of DMF, was added oxalyl chloride (10.9781 mmol, 957.702:l) dropwise at RT After 2 hrs the reaction mixture was concentrated in vacuo to afford 2,3-dimethoxybenzoyl chloride (1.9 g, 90%): 1H NMR (CDCl3, 300 MHz, ppm): 7.52 (m, 1H), 7.12 (d, 2H), 3.89 (s, 3H), 3.88 (s, 3H).
