To a solution of (trans-4-((6-bromo-3-(cyclopropanecarbonyl)quinolin-4-yl)amino)cyclohexyl)methyl methanesulfonate (361 mg, 0.75 mmol) and 2-(methylamino)ethanol (0.30 mL, 3.75 mmol) in acetonitrile (15 mL) was added N,N-diisopropylethylamine (1.0 mL, 5.8 mmol) and the reaction mixture was heated at 70° C. for 16 h. The solution was cooled to room temperature, diluted with a saturated NaHCO3 solution and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated. Purification by column chromatography (silica, 0-20% methanol/dichloromethane) afforded the desired product (150 mg, 43%) as an off-white solid. ESI MS m/z 460 [C23H30BrN3O2+H]+
