Methylamine → 2-amino-6-fluoro-N-methylbenzamide

Participants

Reaction Steps

A round-bottomed flask was charged with 5-fluoro-2H-3,1-benzoxazine-2,4(1H)-dione (500 mg, 2.8 mmol) and 30 mL water. The reaction was stirred for 15 min and then methylamine was added. The reaction was then stirred for 2 h. It was then extracted three times with ethyl acetate. Organic layers were combined and dried over sodium sulfate, then concentrated. The product was identified as 2-amino-6-fluoro-N-methylbenzamide (365 mg, 2.4 mmol, 86% yield). MS: M(C8H9FN2O)=168.17, (M+H)+=169.3.
