Reaction Steps

To a suspension of N-{3-[3-(2-chloro-4-pyrimidinyl)pyrazolo[1,5-a]pyridin-2-yl]phenyl}-2,5-difluorobenzamide (100 mg, 0.22 mmol) (prepared according to a procedure similar to that described in Example 43, Step A) and N-[(3-aminophenyl)methyl]-2,2,2-trifluoroacetamide (59 mg, 0.27 mmol) (prepared as described in Example 180) in 2-propanol (3 mL) was added 2 drops of concentrated HCl. The mixture was heated to 180° C. in a microwave for 15 min. The reaction mixture was diluted with 25 mL EtOAc and washed with saturated aqueous NaHCO3. The organic layer was dried over MgSO4, filtered, and purified by flash chromatography to give the title compound (90 mg, 64% yield). 1H NMR (400 MHz, d6-DMSO): δ 10.64 (s, 1H), 9.99 (t, J=5.7 Hz, 1H), 9.63 (s, 1H), 8.85 (d, J=7.0 Hz, 1H), 8.53 (d, J=8.8 Hz, 1H), 8.27 (d, J=5.3 Hz, 1H), 8.04 (s, 1H), 7.86 (d, J=8.1 Hz, 1H), 7.71 (s, 1H), 7.67 (d, J=8.3 Hz, 1H), 7.42-7.55 (m, 5H), 7.35 (d, J=7.5 Hz, 1H), 7.24 (t, J=7.9 Hz, 1H), 7.14 (t, J=6.8 Hz, 4H), 6.85 (d, J=7.3 Hz, 1H), 6.54 (d, J=5.1 Hz, 1H), 4.35 (d, J=5.8 Hz, 2H). MS (ESI) m/z=645 [M+H]+.
