Anthranilic Acid → Methyl 2-{[(2-methoxyphenyl)acetyl]amino}benzoate

Participants

Reaction Steps

To a mixed solution of acetone (300 ml) and a 6% aqueous potassium carbonate solution (200 ml) there were added 10.2 g (67 mmol) of methyl ester of anthranilic acid. 12.5 g (67 mmol) of 2-Methoxyphenylacetic acid chloride were added dropwise under cooling thereto and the resulting reaction mixture was stirred at room temperature for 4 hours. The resulting precipitates were collected by filtration to obtain 15.7 g (yield 78%) of N-(2-methoxyphenylacetyl)-anthranilic acid methyl ester.
