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), isopropylamine (0.5 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 (0.84 mL, 6 mmol) was stirred at 25° C. for 5 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-isopropylcarbamoyl-1-methyl-ethylamino)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (0.85 g, 94%) as a brown oil which was used for next step without further purification: LC/MS m/e calcd for C27H37N3O3 (M+H)+: 452.61, observed: 452.2.
