실험 절차

Aq NaOH (23.4 mL, 46.8 mmol) was added to a solution of methylamine hydrochloride (3.52 g, 53.7 mmol) in H2O (37 mL). 2,4-dioxo-2,4-dihydro-1H-benzo[d][1,3]oxazine-8-carboxylic acid 29 (3.23 g, 15.6 mmol) was in portions. After addition was complete, the solution was stirred at ambient temperature for 1.5 h. 6M HCl was added until pH=3. The resulting precipitate was collected by filtration, rinsed with H2O and dried to give 31 (2.60 g, 86% yield).
