Versuchsvorschrift

tert-Butyl-4-(4-(6-bromo-7-(4-((2-methylthiazol-4-yl)methyl)piperazin-1-yl)-3H-imidazo[4,5-b]pyridin-2-yl)phenyl)piperazine-1-carboxylate (0.022 g, 0.033 mmol) was suspended in DCM (2.0 mL) and the mixture cooled in an ice bath. TFA (0.5 mL) was added and the resulting solution was allowed to warm up to room temperature and stirred for 2 h. The mixture was passed through an SCX column (5 g), the filtrate collected and the solvent removed in vacuo to give the title compound as a solid (0.016 g, 86%); 1H-NMR (500 Mz, DMSO-d6): δ 2.61-2.70 (m, 7H), 2.81-2.89 (m, 4H), 3.15-3.22 (m, 4H), 3.60-3.68 (m, 6H), 7.03 (d, J=9.0 Hz, 2H, ArH, C6H4), 7.32 (s, 1H, thiazole 5-H), 8.02 (d, J=9.0 Hz, 2H, ArH, C6H4), 8.17 (s, 1H, imidazo[4,5-b]pyridine 5-H); LC (Method B)-MS (ESI, m/z) 2.23 min—553/555 [(M+H)+, Br isotopic pattern]. ESI-HRMS: Found: 553.1522, calculated for C25H30BrN8S (M+H)+: 553.1498.
