The mixture of 3-[[[4-(2-amino-7-chloro-4-quinolinyl)-1-piperazinyl]carbonyl]amino]cyclohexanecarboxylic acid (30 mg, 0.069 mmol), HATU (100 mg), methylamine (1.0M in THF, 3 mL) and diisopropylethylamine (0.5 mL) in DMF (3 mL) was stirred at rt for 3 h. The reaction mixture was diluted with ethyl acetate (100 mL), washed with sat. NaHCO3 solution and water, and dried over Na2SO4. Concentration in vacuo followed by flash chromatography afforded the title product. LC-MS: 445 (M++1). 1H NMR (CD3OD) δ 1.10–1.35 (m, 4H), 1.65–1.90 (m, 4H), 2.20 (m, 1H), 2.65 (s, 3H), 3.08 (m, 4H), 3.60 (m, 5H), 5.80 (d, 1H), 6.15 (s, 1H), 7.10 (d, 2H), 7.45 (s, 1H), 7.65 (a, 1H).
