1-Methyl-1H-pyrrole-2-carbonyl chloride → N-[3-[3-[2-(2,3-dihydro-1,4-benzodioxin-6-ylamino)pyrimidin-4-yl]pyrazolo[1,5-a]pyridin-2-yl]phenyl]-1-methylpyrrole-2-carboxamide

Reaction Steps

To a solution of {4-[2-(3-amino-phenyl)-pyrazolo[1,5-a]pyridin-3-yl]-pyrimidin-2-yl}-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-amine (105 mg, 0.24 mmol) in 5 mL THF was added N-methylpyrrole carbonyl chloride (37 mg, 0.26 mmol). When TLC showed the reaction to be complete, the solution was diluted with DCM and washed with a solution of saturated NaHCO3 and with brine. The organic phase was dried over MgSO4 and concentrated. The residue was triturated with diethyl ether to give the title compound as a yellow solid (119 mg, 92%). 1H NMR (400 MHz, d6-DMSO) δ 9.90 (s, 1H), 9.80 (s, 1H), 8.87 (d, J=6.8 Hz, 1H), 8.50 (s, 1H), 8.14 (d, J=6.0 Hz, 1H), 8.05 (s, 1H), 7.88 (d, J=8.0 Hz, 1H), 7.51 (m, 1H), 7.43 (m, 1H), 7.27-7.22 (m, 2H), 7.17 (t, J=6.8 Hz, 1H), 7.05-7.04 (m, 2H), 7.00 (s, 1H), 6.81 (d, J=8.4 Hz, 1H), 6.47 (d, J=6.0 Hz, 1H), 6.08-6.07 (m, 1H), 4.22 (m, 4H), 3.85 (s, 3H) ppm.
