Procedure

To a solution of 2-(3-amino-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (220 mg, 0.74 mmol) in tetrahydrofuran (5 mL) and triethyl-amine (0.2 mL, 1.48 mmol) was added 3-fluorophenyl isocyanate (0.1 mL, 0.89 mmol) dropwise. The reaction mixture was stirred at 25° C. for 1 h. Then the reaction mixture was concentrated in vacuo and the residue was extracted with ethyl acetate (2×30 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. Purification by Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% formic acid in water) afforded 2-{3-[3-(3-fluoro-phenyl)-ureido]-phenyl}-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (67 mg, 20%) as a white solid: LC/MS m/e calcd for C25H24FN3O3 (M+H)+: 434.49, observed: 434.1.
