Procedure

To a solution of 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-2-(2-hydroxyphenyl)ethyl]aminocarbonyl-4-methoxyquinoline (200 mg, 0.39 mmol) in DMF (5 mL) was added CsCO3 (260 mg, 0.8 mmol) and ethyl bromoacetate (120 mg, 0.7 mmol) and the reaction mixture was stirred at ambient temperature for 6 hours. The reaction mixture was partitioned in water and ethyl acetate and extracted with ethyl acetate. Combined organic layers were washed with water, brine, dried over sodium sulfate and concentrated. The residue was purified by preparative HPLC to afford 2-[1-(4-(ethoxycarbonyl)piperazin-1-yl)carbonyl-2-(2-(ethoxycarbonyl)methoxyphenyl)ethyl]aminocarbonyl-4-methoxyquinoline as a white solid 140 mg (60%); NMR (DMSO-d6), 1.18 (m, 6), 3.26 (m, 10), 4.00 (q, 2), 4.04 (s, 3), 4.84 (s, 2), 5.26 (m, 1), 6.82 (q, 1), 7.88 (d, 1), 7.48 (s, 1), 7.64 (t, 1), 7.82 (t, 1), 8.06 (d, 1), 8.16 (d, 1), 8.86 (d, 1) ppm.
