Versuchsvorschrift

A solution of N-(imidazo[1,2-a]pyridin-7-ylmethyl)-5-{1-[(4-methylpiperidin-4-yl)methyl]-1H-pyrazol-4-yl}thiophene-2-carboxamide (0.100 g, 0.197 mmol) in N,N-dimethylformamide (2 ml) was added tert-butyl 4-(2-bromoethyl)piperazine-1-carboxylate (0.058 g, 0.197 mmol) followed by N,N-diisopropylethylamine (0.138 ml, 0.788 mmol) and the reaction was stirred overnight. The reaction mixture was purified directly using normal phase chromatography and the resulting material was treated with HCl in dioxane (4M) for 2 hours then concentrated to give the title compound as a hydrochloride salt. 1H NMR (500 MHz, DMSO-d6) δ 14.64 (s, 1H), 10.40 (s, 1H), 9.72 (s, 1H), 9.54 (t, J=6.0 Hz, 1H), 8.89 (d, J=6.9 Hz, 1H), 8.34 (d, J=1.8 Hz, 1H), 8.22 (s, 1H), 8.16 (d, J=2.1 Hz, 1H), 7.91 (d, J=3.9 Hz, 1H), 7.87 (s, 1H), 7.83 (s, 1H), 7.50 (dd, J=7.0, 1.4 Hz, 1H), 7.28 (d, J=3.8 Hz, 1H), 4.64 (d, J=5.8 Hz, 2H), 4.23-3.54 (m, 10H), 3.35 (d, J=38.3 Hz, 8H), 1.72 (d, J=77.7 Hz, 4H), 0.98 (s, 3H); MS (ESI(+)) m/e 547 (M+H)+.
