Reaction Steps

3-Methyl-N(chloroacetyl)anthranilic acid 7.5 g (33 mmol)(synthesized from 3-methylanthranilic acid by the same procedures as those of Example 9) and m-toluidine 11 ml (0.10 mol) were dissolved in 60 ml of dimethylformamide and heated at 90° C. for 4 hours. The reaction solution was poured into ice water and extracted with ether. The resulting ether solution was extracted with 10% sodium hydroxide and the resluting aqueous solution was neutralized with 10% HCl solution. The neutralized solution was extracted with ether, and the ether solution was washed with water and dried. The solvent was distilled off and the residue was recrystallized from benzene-toluene to obtain 3-methyl-N[(3-methylphenyl)acetyl]anthranilic acid 4.8 g (yield: 49%).
