Versuchsvorschrift

A solution of 2-(3-bromo-phenyl)-1,4,4-trimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonitrile (354.0 mg, 1.0 mmol), copper(I) iodide (57.0 mg, 0.3 mmol), 1-amino-cyclopropanecarboxylic acid (309.0 mg, 3.0 mmol) and potassium carbonate (415.0 mg, 3.0 mmol) in dimethyl sulfoxide (2.0 mL) was stirred at 120° C. for 16 h. Then the reaction mixture was cooled to room temperature and extracted with ethyl acetate (150 mL×2), washed with water (50 mL×2) and saturated aqueous ammonium chloride solution (50 mL×2), dried over anhydrous sodium sulfate and then 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% ammonium hydroxide in water) afforded 1-[3-(6-cyano-1,4,4-trimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamino]-cyclopropanecarboxylic acid (113.4 mg, 30.1%) as a white solid: LC/MS m/e obsd. (ESI+) [(M+H)+] 376.3.
