Procedure

A slurry of ethyl {7-chloro-4-[(3-oxo-3,4-dihydro-2H-1,4-benzoxazin-6-yl)carbonyl]-3,4-dihydro-2H-1,4-benzoxazin-3-yl}acetate (Intermediate 21, 0.39 g, 0.91 mmol) in a mixture of MeOH (5 mL) and a 33% solution of methanamine (15 mL, 0.91 mmol) in EtOH was stirred at rt over night giving clean conversion to the amide. The reaction mixture was concentrated under reduced pressure giving the title compound (0.370 g, 98%) as a white solid.
