Versuchsvorschrift

3-Methylanthranilic acid 5 g (33 mmol) was dissolved in 10% aqueous sodium hydroxide solution 27 ml and to this solution, phenoxyacetyl chloride 6.2 g (36 mmol) was added dropwise at 0° C. The resulting solution was stirred at room temperature for 1 hour and acidified with 10% hydrochloric acid solution. Deposited crystals were collected by filtration, washed with water and recrystallized from ethanol to obtain 3-methyl-N-(phenoxyacetyl)anthranilic acid (melting point: 174° to 176° C.) 4.4 g (yield: 47%).
