Vorschrift

The same operation as in Example (90a) was performed using 7-nitro-2,3-dihydro-4H-1,4-benzoxazine (described in Higuchi, Robert I.; Arienti, Kristen L.; Lopez, Francisco J.; Mani, Neelakhanda S.; Mais, Dale E.; Caferro, Thomas R.; Long, Yun Oliver; Jones, Todd K.; Edwards, James P.; Zhi, Lin; Schrader, William T.; et al.; J. Med. Chem.; 50; 10; 2007; 2486-2496, 0.6 g, 3.3 mmol), sodium hydride (55% content, 145 mg, 3.3 mmol), methyl 4-bromomethylbenzoate (0.76 g, 3.3 mmol) and DMF (20 mL). The resulting solid was washed with ethyl acetate/hexane=1/1 to obtain 0.98 g of the title compound as a yellow solid (90%).
