| Product | HCID 21447078 | HCID 21447078 | 49.3% |
Reaction Steps
The benzoxazinone of Example 1 (15.31 g., 0.071 mole) was added to a solution of methylhydrazine (3.90 g., 0.085 mole) in acetic acid (150 ml.) and the resultant solution was stirred at 80° C. for 2.5 hours. The solvent was removed and the product was recrystallized (acetonitrile) to yield N-(1,3-dimethyl-5-pyrazolyl)-4-methylanthranilic acid (8.59 g., 49 percent), mp 188°-192° C.
