Versuchsvorschrift

To a solution of {4-[2-(3-amino-phenyl)-pyrazolo[1,5-a]pyridin-3-yl]-pyrimidin-2-yl}-phenyl-amine (40 mg, 0.105 mmol) in mixture of DCM (1.2 mL) and pyridine (0.3 mL) was added nicotinoyl chloride hydrochloride (23 mg, 0.11 mmol). The resultant mixture was stirred at rt for 12 h. The resultant precipitate was collected by filtration, and washed with water and diethyl ether to give N-{3-[3-(2-phenylamino-pyrimidin-4-yl)-pyrazolo[1,5-a]pyridin-2-yl]-phenyl}-nicotinamide (19 mg). 1H NMR (400 MHz, DMSO-d6) δ 6.56 (m, 1H), 6.95 (m, 1H), 7.15 (m, 1H), 7.27 (m, 2H), 7.36 (m, 1H), 7.51 (m, 2H), 7.62 (m, 1H), 7.71 (m, 2H), 7.96 (m, 1H), 8.11 (m, 1H), 8.17 (m, 1H), 8.35 (m, 1H), 8.50 (m, 1H), 8.79 (m, 1H), 8.86 (m, 1H), 9.13 (m, 1H), 9.64 (s, 1H), 10.6 (s, 1H). LC/MS: m/z 484 (M+1)+.
