Procedure

A mixture of 5-amino-6,7-difluoro-1,4-dihydro-4-oxo-1-(tetrahydropyran-4-yl)-3-quinolinecarboxylic acid (45.0 mg, 0.139 mmol), 2-(2-pyridylamino)ethylamine (29.0 mg, 0.211 mmol), and triethylamine (0.029 mL, 0.209 mmol) in DMSO (1.0 mL) was stirred at 120° C. for 3 h. After dilution of the reaction mixture with 10% MeOH in CHCl3, the whole mixture washed with water, and the washing was extracted with 10% MeOH in CHCl3 two times. The combined the organic layer and the extracts washed with water, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. Flash chromatography of the residue (10% MeOH in CHCl3) gave 5-Amino-6-fluoro-1,4-dihydro-4-oxo-1-(tetrahydropyran-4-yl)-7-[2-(2-pyridylamino)ethylamino]-3-quinolinecarboxylic Acid (54.0 mg, 88%) as a white powder.
