Procedure

A suspension of N-(imidazo[1,2-a]pyridin-7-ylmethyl)-5-{1-[(4-methylpiperidin-4-yl)methyl]-1H-pyrazol-4-yl}thiophene-2-carboxamide (0.139 g, 0.274 mmol), 2,2-dimethyl-4-oxo-3,8,11,14,17-pentaoxa-5-azaicosan-20-oic acid (0.100 g, 0.274 mmol), 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.104 g, 0.274 mmol) and 4-methylmorpholine (0.105 ml, 0.958 mmol) was stirred at room temperature for 3 hours. The reaction mixture was purified directly by normal phase chromatography and the resulting material was treated with HCl/dioxane (4 M) then concentrated to give the title compound as a hydrochloride salt. 1H NMR (400 MHz, DMSO-d6) δ 14.71 (s, 1H), 9.58 (t, J=6.0 Hz, 1H), 8.89 (d, J=7.0 Hz, 1H), 8.35 (d, J=1.9 Hz, 1H), 8.16 (d, J=2.1 Hz, 2H), 8.06 (s, 3H), 7.92 (d, J=3.9 Hz, 1H), 7.83 (s, 2H), 7.50 (dd, J=7.0, 1.2 Hz, 1H), 7.26 (d, J=3.8 Hz, 1H), 4.64 (d, J=5.8 Hz, 2H), 4.05 (s, 2H), 3.80 (dd, J=11.8, 6.8 Hz, 2H), 3.66-3.58 (m, 4H), 3.55 (dd, J=9.2, 4.4 Hz, 4H), 3.50 (t, J=7.5 Hz, 8H), 3.37-3.26 (m, 1H), 3.23-3.13 (m, 1H), 2.99-2.90 (m, 2H), 2.55 (t, J=6.6 Hz, 2H), 1.53-1.19 (m, 4H), 0.95 (s, 3H); MS (ESI(+)) m/e 682 (M+H)+.
