반응 단계
The suspension of 9.87 g of 6-bromo-4H-benzo[1,4]oxazin-3-one [CAS 24036-52-0], 9.40 g of 1-chloro-3-methoxypropane, potassium fluoride on alumina (Fluka 60244), 0.144 g of potassium iodide in 500 ml of acetonitrile is stirred at 100° C. over 40 hours. The reaction mixture is cooled to room temperature and filtered through Hyflo, and the filtrate is concentrated by evaporation to dryness. The title compound is obtained as a slightly yellowish solid from the residue by crystallization from ethyl acetate. Rf=0.43 (1:1 EtOAc-heptane). Rt=4.27 (gradient I). m.p. 193-195° C.
