実験手順

To a solution of 4-[2-(3-aminophenyl)pyrazolo[1,5-a]pyridin-3-yl]-N-phenyl-2-pyrimidine (30 mg, 0.08 mmol) (see Example 3, Step H) in THF (3 mL) was added CDI (14 mg, 0.09 mmol). The resultant mixture was stirred at rt for 1 hour. To the mixture was added (3-chlorophenyl)acetic acid (15 mg, 0.09 mmol) and then stirred at rt for 15 h. Methanol (2 mL) was added and the mixture was concentrated in vacuo. The residue was purified by chromatography on silica gel (hexanes/EtOAc) to give the title compound (25 mg, 60% yield). 1H NMR (400 MHz, DMSO-d6): δ 3.68 (s, 2H), 6.53 (d, 1H, J=5.3 Hz), 6.92 (m, 1H), 6.92 (m, 1H), 7.12 (m, 1H), 7.21-7.50 (m, 9H), 7.68-7.76 (m, 3H), 7.89 (m, 1H), 8.26 (d, 1H, J=5.3 Hz), 8.47 (m, 1H), 8.83 (d, 1H, J=6.8 Hz), 9.56 (s, 1H), 10.35 (s, 1H). ES-LC/MS m/z=531 [M+H]+.
