Procedure

To a stirred solution of phenylacetic acid (850 mg, 6.2 mmol), 2-(1H-7-Azabenzotriazol-1-yl)-1,1,3,3-tetramethyl uronium hexafluorophosphate Methanaminium (HATU) (3.5 g, 9.3 mmol) and triethyl amine (2.6 mL, 18.6 mmol) in dichloromethane (20 mL) was added 2-(3-amino-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (2.0 g, 6.2 mmol) at room temperature and stirred at room temperature for overnight. Then the reaction mixture was concentrated in vacuo and the residue was extracted with ethyl acetate (2×200 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo to afford 3,3-dimethyl-2-(3-phenylacetylamino-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (2.7 g, quant.) as a light yellow solid which was used for next step without further purification: LC/MS m/e calcd for C28H30N2O3 (M+H)+: 443.56, observed: 443.1.
