実験手順

A mixture solution of 2-(3-bromo-phenyl)-4,4-dimethyl-6-(morpholine-4-sulfonyl)-1,2,3,4-tetrahydro-quinoline (150 mg, 0.33 mmol), copper(I) iodide (20 mg, 0.1 mmol), 2-amino-2-methyl-propionic acid (135 mg, 1.3 mmol) and potassium carbonate (110 mg, 1.0 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 (70 mL×2), washed with water (30 mL×3) and saturated aqueous ammonium chloride solution (30 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 2-{3-[4,4-dimethyl-6-(morpholine-4-sulfonyl)-1,2,3,4-tetrahydro-quinolin-2-yl]-phenylamino}-2-methyl-propionic acid (90 mg, 56.0%) as a white solid: MS (ESI) M+1=488.0.
