Versuchsvorschrift

Methyl 2-fluoro-4-[3-(1-quinolin-6-ylcyclopropyl) [1,2,4]triazolo[4,3-b][1,2,4]triazin-6-yl]benzoate (0.15 g, 0.34 mmol) was dissolved in a solution of tetrahydrofuran (3 mL), methanol (1 mL) and water (1 mL) under N2 atmosphere. To the solution was added lithium hydroxide aqueous solution (2.0 M, 0.30 mL) with stirring. The mixture was stirred at RT for 1 h, and acidified with 1.0 M of hydrogen chloride in water (0.68 mL). The organic solvents were removed. The formed precipitate was collected by filtration, and dried in-vacuo to afford the desired product (120 mg). Analytical LCMS: (M+H)+=427.0.
