Reaction Steps

5-((2S,4R)-1-acetyl-4-((5-cyanopyrazin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)picolinic acid (for a preparation see Intermediate 53) (100 mg, 0.233 mmol), HATU (177 mg, 0.467 mmol) and DIPEA (0.122 ml, 0.700 mmol) were combined in DMF (3 mL) and stirred at room temperature for 10 mins. 2-aminoethanol (0.029 ml, 0.350 mmol) was added and the reaction mixture stirred for 1.5 h. The mixture was concentrated in vacuo and purified by MDAP (formate) to give 5-((2S,4R)-1-acetyl-4-((5-cyanopyrazin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)-N-(2-hydroxyethyl)picolinamide (42 mg, 0.089 mmol, 38% yield). LCMS: (Formate, 2 min), Rt=0.73 mins, MH+=472
