Reaction Steps

To a solution of 4-amino-5-chloro-2-methoxybenzoic acid (20.0 g, 99.2 mmol) in methanol (250 mL) was added thionyl chloride (7.2 mL, 99.2 mmol). The reaction was refluxed for 16 h then concentrated in vacuo. Purification by silica gel chromatography (0-90% ethyl acetate/hexanes) provided methyl 4-amino-5-chloro-2-methoxybenzoate (21.3 g, quantitative yield). LC/MS m/z 216.3 [M+H]+.
