Versuchsvorschrift

To a solution of tert-butyl (4,6-dimethyl-5-((1-((7-methylquinolin-3-yl)methyl)-1H-1,2,3-triazole-4-carboxamido)methyl)pyridin-2-yl)carbamate (70 mg, 0.140 mmol) in DCM (1 ml) was added TFA (0.215 ml, 2.79 mmol). Reaction mixture was stirred over a weekend at 23° C. Reaction mixture was evaporated to afford a crude product, which was purified by preparative HPLC (Sunfire C18-ODB, 5 μm, 100×30 mm, elution with A=water+0.1% HCOOH and B=ACN+0.1% HCOOH, gradient from 10% to 100% B in 25 min, flow: 40 mL/min). Fractions were combined and solvents were evaporated to afford athe product as a formic acid salt, which was dissolved in methanol and eluted through a PL-HCO3 MP-resin column (Stratosphere SPE) in order to remove salt. The eluted solution was evaporated and dried overnight under high vacuum (dessicator, 50° C.) to afford the title compound as a free base. 1H-NMR (DMSO-d6, 400 MHz) δ 8.90 (s, 1H), 8.72 (s, 1H), 8.30 (broad s, 1H), 8.26 (s, 1H), 7.89 (d, 1H), 7.83 (s, 1H), 7.49 (d, 1H), 6.10 (s, 1H), 5.87 (s, 2H), 5.61 (broad s, 2H), 4.33 (d, 2H), 2.54 (s, 3H), 2.31 (s, 3H), 2.18 (s, 3H); HPLC (Method G) Rt=1.079 min; MS (Method V) [M+H]+=402.4.
