Reaction Steps

A solution of 6-hydroxy-1H-benzo[d][1,3]oxazine-2,4-dione (500 mg, 2.79 mmol) in ethanol (20 mL) was cooled to 0° C. and methylamine solution (33% in ethanol, 2.92 mL, 27.9 mmol) added and the reaction stirred for 3 days. The solvent was removed under reduced pressure and the product purified by silica chromatography, eluent 5% methanol in dichloromethane to yield 2-amino-5-hydroxy-N-methylbenzamide (280 mg, 1.68 mmol).
