Procedure

To a solution of N-{4-[2-(3-aminophenyl)pyrazolo[1,5-a]pyridin-3-yl]-5-fluoro-2-pyrimidinyl}-2-methyl-1,2,3,4-tetrahydro-7-isoquinolinamine (50 mg, 0.11 mmol) in THF (5 mL) was added 2,6-difluorobenzoyl chloride (20 mg, 0.11 mmol) and the reaction mixture stirred at rt for 20 min. The reaction was diluted with MeOH, adsorbed to silica gel, and purified by column chromatography (0-10% MeOH/DCM+1% NH4OH) to afford the title compound (15.4 mg, 24%) as a pale yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 10.86 (s, 1H), 9.52 (s, 1H), 8.86 (d, J=7.69 Hz, 1H), 8.45-8.46 (m, 1H), 8.06 (s, 1H), 7.89 (d, J=8.61 Hz, 1H), 7.71-7.73 (m, 1H), 7.54-7.58 (m, 1H), 7.30-7.47 (m, 4H), 7.20-7.24 (m, 3H), 7.08-7.12 (m, 1H), 6.86 (d, J=8.42 Hz, 1H), 3.26 (s, 2H), 2.66-2.69 (m, 2H), 2.49-2.51 (m, 2H), 2.26 (s, 3H); ESIMS (M+H)+=606.
