Versuchsvorschrift

To a solution of 4-[2-(3-aminophenyl)pyrazolo[1,5-a]pyridin-3-yl]-N-(3-fluorophenyl)-2-pyrimidinamine (92 mg, 0.23 mmol) in 2 mL of THF, added 2-chloro-6-fluorobenzoyl chloride (48 mg, 0.27 mmol). The reaction was stirred for 30 min at rt and quenched by addition of polystyrene-trisamine resin (20 mg). The reaction was allowed to stir overnight. The reaction was treated with excess Et3N, filtered, and washed with THF. The filtrate was collected, reduced in vacuo, and upon treatment with DCM, a white solid formed. Filtration and washing with the solid with Et2O yielded the desired product as a white solid, 96 mg, 65% yield. 1H NMR (400 MHz, d6-DMSO): δ 10.89 (s, 1H); 9.78 (s, 1H); 8.84 (d, J=6 Hz, 1H); 8.30 (d, J=5 Hz, 1H); 8.00 (s, 1H); 7.77-7.23 (m, 2H); 7.55-7.33 (m, 7H); 7.22 (q, J=8 Hz, 1H); 7.11 (t, J=7 Hz, 1H); 6.69 (td, J=2, 8 Hz, 1H); 6.60 (d, J=5 Hz, 1H). HRMS calculated C30H20ClF2N6O [M+H]+ 553.1355, found 553.1360.
