Procedure

To a flask charged with 6-((2S,4R)-1-acetyl-4-((5-cyanopyridin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)nicotinic acid (for a preparation see Intermediate 7) (90 mg, 0.211 mmol) and HATU (96 mg, 0.253 mmol) was added DMF (3 mL) and the resulting mixture was treated with DIPEA (0.110 mL, 0.632 mmol). After stirring for 5 min, the mixture was treated with 2-aminopropane-1,3-diol (38.4 mg, 0.421 mmol). After stirring for 3 min, the solution was partitioned between EtOAc and saturated aqueous NaHCO3 solution and the layers were separated. The aqueous phase was extracted with EtOAc (×2) and the combined organic layers were washed with saturated aqueous NaHCO3 solution (×3), then dried over MgSO4 and concentrated in vacuo. The residue was purified by MDAP (HpH). The appropriate fractions were collected and concentrated in vacuo. The residue was subsequently dissolved in MeOH and dried (hydrophobic frit). The solvent was removed and the residue triturated in Et2O to give 6-((2S,4R)-1-acetyl-4-((5-cyanopyridin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)-N-(1,3-dihydroxypropan-2-yl)nicotinamide (26 mg, 0.052 mmol, 24.67% yield) as a white solid.
