Participants

Reaction Steps

To a solution of 2-(4-((2S,4R)-1-acetyl-4-((5-cyanopyridin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)phenyl)acetic acid, lithium salt (for a preparation see Intermediate 9)(125 mg, 0.284 mmol) and N1,N1-dimethylethane-1,2-diamine (32.5 mg, 0.369 mmol) in DMF (3 mL) were added HATU (162 mg, 0.426 mmol) and DIPEA (0.149 mL, 0.851 mmol). The resulting mixture was stirred at room temperature for 2 h, the reaction mixture was diluted with EtOAc and water. The layers were separated and the aqueous phase was extracted with EtOAc (×3). The combined organic layers were washed with brine, dried over MgSO4, filtered and concentrated in vacuo. The crude residue was dissolved in 1:1 MeOH/DMSO and was purified by MDAP (formate). The appropriate fractions were combined and concentrated in vacuo to give 2-(4-((2S,4R)-1-acetyl-4-((5-cyanopyridin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)phenyl)-N-(2-(dimethylamino)ethyl)acetamide (59 mg, 41%) as a colourless oil. LCMS (Formate, 2 min), Rt=0.65 min, MH+=511.
