実験手順

To a solution of {4-[2-(3-amino-phenyl)-pyrazolo[1,5-a]pyridin-3-yl]-pyrimidin-2-yl}-(3-fluoro-phenyl)-amine (80 mg, 0.20 mmol) in 2 mL THF was added 2-chloro-5-fluorobenzoyl chloride (26 μL, 0.22 mmol). When LC/MS indicated the reaction was complete, several equivalents of PS-trisamine were added and the mixture was stirred for 16 h. Et3N was added if necessary to get the reaction into solution. The mixture was filtered and the resin washed well with THF. The filtrate was concentrated and triturated with DCM to give the title compound (51 mg, 46%). 1H NMR (400 MHz, d6-DMSO) δ 10.66 (s, 1H), 9.78 (s, 1H), 8.84 (d, J=6.8 Hz, 1H), 8.45 (d, J=8.8 Hz, 1H), 8.30 (d, J=5.2 Hz, 1H), 8.01 (s, 1H), 7.80-7.74 (m, 2H), 7.61-7.42 (m, 5H), 7.39-7.32 (m, 2H), 7.26-7.20 (m, 1H), 7.11 (t, J=6.4 Hz, 1H), 6.72-6.67 (m, 1H), 6.57 (d, J=5.2 Hz, 1H) ppm. MS (ESI) m/z=553 [M+H]+.
