Procedure

To a solution of 4-{(2S,4R)-1-acetyl-4-[(4-chlorophenyl)amino]-2-methyl-1,2,3,4-tetrahydro-6-quinolinyl}benzoic acid (for a preparation see Intermediate 18) (250 mg, 0.575 mmol) in DMF (10 mL) were successively added 3-(dimethylamino)-1-propanol (71.2 mg, 0.690 mmol), EDC (220 mg, 1.150 mmol) and DMAP (7.0 mg, 0.057 mmol). The resulting mixture was stirred at room temperature overnight, then concentrated in vacuo, dissolved in a 1:1 MeOH/DMSO mixture and purified by MDAP (HpH). The appropriate fractions were combined and concentrated under reduced pressure to give 3-(dimethylamino)propyl 4-((2S,4R)-1-acetyl-4-((4-chlorophenyl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)benzoate (41 mg, 17%) as a viscous colourless oil. LCMS (Formate, 2 min), Rt=0.94 min, MH+=520.
