Procedure

A mixture of (3S)-8-Amino-9,10-difluoro-2,3-dihydro-7-oxo-3-phenylmethyl-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid (76.9 mg, 0.207 mmol), 2-(2-pyridylamino)ethylamine (41.8 mg, 0.303 mmol), and triethylamine (42.1 μL, 0.302 mmol) in DMSO (1.5 mL) was stirred at 100° C. for 3 h. The reaction mixture was poured into ice-water and the resulting precipitates were collected by filtration. Recrystallization of the filtered precipitates from CH2Cl2-EtOH gave (3S)-8-amino-9-fluoro-2,3-dihydro-7-oxo-3-phenylmethyl-10-[2-(2-pyridylamino)ethylamino]-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid (55.4 mg, 55%) as a yellow powder.
