Reaction Steps

The mixture of 4,4-dimethyl-2-(3-bromo-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid methyl ester as prepared according to Example 1 (374 mg, 1 mmol), CuI (60 mg, 0.3 mmol), L-proline (70 mg, 0.6 mmol) and morpholine (440 mg, 5 mmol) in DMSO (5 mL) was stirred at 120° C. for 16 hours under a nitrogen atmosphere. The reaction mixture was diluted with water (20 mL), extracted with ethyl acetate (20 mL×3) and washed with brine (100 mL) and then dried over anhydrous Na2SO4. The solvent was removed in vacuo and the residue was purified by ISCO combi-flash chromatography (gradient elution, 30-60% ethyl acetate in petroleum ether) to afford 4,4-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid methyl ester (200 mg, 52.6%) as a white solid. MS (ESI+) [(M+H)+] 381.1.
