Procedure

2-[3-(1-carboxy-1-methyl-ethylamino)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (820 mg, 2 mmol), 1-methyl-piperazine (0.67 mL, 6 mmol) and o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1140 mg, 3 mmol) in dichloromethane (10 mL) and triethyl-amine (1.7 mL, 12 mmol) was stirred at 25° C. for 24 h. Then the reaction mixture was extracted with dichloromethane (2×100 mL), washed with water, dried over anhydrous sodium sulfate and concentrated in vacuo to afford 2-{3-[1,1-dimethyl-2-(4-methyl-piperazin-1-yl)-2-oxo-ethylamino]-phenyl}-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (0.895 g, 91%) as a brown oil which was used for next step without further purification: LC/MS m/e calcd for C29H40N4O3 (M+H)+: 493.67, observed: 493.2.
