Procedure

A mixture of 2-(3-carbonyl-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (720 mg, 2 mmol), phenylamine (224 mg, 2.4 mmol) and o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1.14 g, 3 mmol) in dichloromethane (5 mL) and triethyl-amine (0.7 mL, 5 mmol) was stirred at 25° C. for 12 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 3,3-dimethyl-2-(3-phenylcarbamoyl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (0.8 g, 93%) as a brown oil which was used for next step without further purification: LC/MS m/e calcd for C27H28N2O3 (M+H)+: 429.54, observed: 429.1.
