Anthranilic Acid → Methyl Anthranilate

Participants

Reaction Steps

To a stirred solution of 2-aminobenzoic acid (2.0 g, 14.59 mmol) in MeOH (70 mL) at 0° C. was added SOCl2 (7.4 g, 145.9 mmol) dropwise. The mixture was heated at reflux overnight and was then concentrated under reduced pressure. DCM and saturated aqueous NaHCO3 were added and the aqueous phase extracted with DCM. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to afford methyl 2-aminobenzoate (2.05 g, 93%). LC-MS (ES-API); rt 8.46 min; m/z calculated for C8H9NO2[M+H]+ 152.0, found 152.1.
