Procedure

To a stirred solution of 4-[2-(3-amino-4-fluorophenyl)pyrazolo[1,5-a]pyridin-3-yl]-N-{3-[(dimethylamino)methyl]phenyl}-2-pyrimidinamine (58 mg, 0.13 mmol) in THF (3 mL) was added TEA (27 μL, 0.19 mmol) and 2-thiopheneacetyl chloride (17 μL, 0.13 mmol). After 20 h, the reaction mixture was diluted with EtOAc (20 mL), adsorbed onto silica gel, and purified by column chromatography to give the title compound (58 mg, 77% yield). 1H NMR (400 MHz, d6-DMSO) 610.15 (s, 1H), 9.54 (s, 1H), 8.83 (d, J=7.0 Hz, 1H), 8.48 (d, J=8.8 Hz, 1H), 8.26-8.29 (m, 2H), 7.69 (s, 1H), 7.63 (d, J=8.2 Hz, 1H), 7.47 (t, J=7.9 Hz, 1H), 7.36-7.39 (m, 2H), 7.18 (t, J=7.8 Hz, 1H), 7.13 (t, J=6.9 Hz), 6.96-6.98 (m, 2H), 6.87 (d, J=7.1 Hz, 1H), 6.52 (d, J=5.3 Hz, 1H), 3.99 (s, 2H), 3.32 (s, 2H), 2.15 (s, 6H). ES-LC/MS m/z=578 [M+H]+.
