A solution of 8-amino-9,10-difluoro-7-oxo-2,7-dihydrospiro[[1,4]oxazino[2,3,4-ij]-quinoline-3,1′-cyclopentane]-6-carboxylic acid (13 mg, 0.04 mmol) and N1-(4-methylquinolin-2-yl)ethane-1,2-diamine (10 mg, 0.05 mmol) and 11 μL triethylamine in DMSO (0.3 mL) was stirred at 90° C. for 72 h. The reaction mixture was cooled and freeze-dried overnight. The crude product was taken up in CH2Cl2 and purified by preparative TLC to yield 8-amino-9-fluoro-10-(2-(4-methylquinolin-2-ylamino)ethylamino)-7-oxo-2,7-dihydrospiro[[1,4]oxazino[2,3,4-ij]quinoline-3,1′-cyclopentane]-6-carboxylic acid (0.8 mg, 4%) as a yellow solid. MS (EP) m/z: 518 (M++1). (Calcd. for C28H28FN5O4, 517.21).
