Versuchsvorschrift

Lithium hydroxide monohydrate (83 mg, 1.97 mmol) in water (5 mL) was added to methyl 5-((2S,4R)-1-acetyl-4-((5-cyanopyrazin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)picolinate (for a preparation, see Intermediate 52) (435 mg, 0.983 mmol) in 1,4-dioxane (5 mL) and the reaction mixture stirred at room temperature for 70 mins. Acetic acid (0.169 mL, 2.95 mmol) was added and the resulting mixture stirred for 10 mins. The mixture was filtered, the solid collected was washed with water, then dried in a vacuum oven to give 5-((2S,4R)-1-acetyl-4-((5-cyanopyrazin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)picolinic acid (181 mg, 0.422 mmol, 43% yield) as a brown solid. LCMS: (Formate, 2 min) Rt=0.66 mins, MH+=429.
