실험 절차

To a suspension of 3,5-dichloro-4-[4-(6-hydroxymethyl-pyrimidin-4-ylamino)-pyrazolo[4,3-c]pyridin-2-yl]-benzonitrile (70 mg, 0.17 mmol) in DCM (5 mL) at −25° C. was added DAST (34 μL, 0.25 mmol). The reaction mixture was warmed to room temperature over 1 hour. The reaction mixture was partitioned between DCM and sodium bicarbonate (sat. aq.). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (0-100% ethyl acetate in cyclohexane) then by HPLC (5 to 98% acetonitrile in water with 0.1% ammonium hydroxide) to afford the title compound as a white solid (10 mg, 14% yield). 1H NMR (400 MHz, DMSO-d6): δ 10.96 (s, 1H), 9.23 (s, 1H), 8.81 (s, 1H), 8.69 (s, 1H), 8.49 (s, 2H), 8.02 (d, J=6.4 Hz, 1H), 7.27 (d, J=6.4 Hz, 1H), 5.50 (d, J=46.3 Hz, 2H). LCMS (Method B): RT=2.96 min, m/z: 414 [M+H+].
