Reaction Steps

A mixture of 2-(3-bromo-phenyl)-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (360 mg, 1 mmol), 2-amino-2-methyl-propan-1-ol (0.48 mL, 5 mmol), copper(I) iodide (115 mg, 0.6 mmol), N,N-dimethylglycine hydrochloride (112 g, 0.8 mmol) and potassium carbonate (415 mg, 3 mmol) in dimethyl sulfoxide (5 mL) was stirred at 120° C. for 16 h. Then the reaction mixture cooled to room temperature. The reaction mixture was extracted with ethyl acetate (2×150 mL), washed with water (2×50 mL) and saturated aqueous ammonium chloride solution (2×50 mL), 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% formic acid in water) afforded 2-[3-(2-hydroxy-1,1-dimethyl-ethylamino)-phenyl]-3,3-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (8 mg, 2%) as a white powder: LC/MS m/e calcd for C22H28N2O3 (M+H)+: 369.48, observed: 369.1.
