Versuchsvorschrift
To a solution of N-{4-[4-(4-chlorobenzyl)-5-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-5-yl)-1,3-thiazol-2-yl]pyridin-2-yl}acetamide (0.112 g, 0.207 mmol) in dichloromethane (2.0 mL) at room temperature was added trifluoroacetic acid (3.1 mL, 40 mmol). The mixture was then stirred at room temperature for 4 hours. The solvent was evaporated and the excess trifluoroacetic acid was removed by azeotroping with toluene. Column chromatography was performed to yield the title compound (0.0520 g, 61%). LCMS: (FA) ES+ , 411. 1H NMR (400 MHz, d6-DMSO) δ: 14.46 (s, 1H), 10.69 (s, 1H), 8.80-8.73 (m, 1H), 8.64-8.60 (m, 1H), 8.43-8.37 (m, 1H), 7.59-7.54 (m, 1H), 7.37-7.28 (m, 4H), 4.66 (s, 2H), 2.12 (s, 3H).
