Reaction Steps

To a solution of 2-(3-amino-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (324 mg, 1 mmol) in dichloromethane (5 mL) and pyridine (0.5 mL, 6 mmol) was added a solution of morpholine-4-carbonyl chloride (0.12 mL, 1 mmol) in dichloromethane (2 mL) dropwise at 0° C. The reaction mixture was stirred at 25° C. for 5 h. Then the reaction mixture was extracted with dichloromethane (2×50 mL), washed with water, dried over anhydrous sodium sulfate and concentrated in vacuo to afford 3,3-dimethyl-2-{3-[(morpholine-4-carbonyl)-amino]-phenyl}-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (437 mg, 100%) as a brown oil which was used for next step without further purification: LC/MS m/e calcd for C25H31N3O4 (M+H)+: 438.54, observed: 438.2.
