实验步骤: A mixture of 3,6-dichloro-1H-pyrazolo[4,3-c]pyridine (583.6 mg, 3.10 mmol), 1-(2-methoxyethyl)urea (550 mg, 4.66 mmol), chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′-4′-6′-tri-1-propyl-1,1′-biphenyl][2-(2-aminoethyl)phenyl]palladium(II) (248 mg, 0.310 mmol) and 1.78 M KOtBu in THF (5231 μl, 9.31 mmol) was degassed and then THF (0.5 mL) was added. The reaction mixture was heated to 60° C. overnight. The reaction was diluted with ethyl acetate and washed with water. The combined organics were dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by MPLC (0-30% MeOH-DCM) gave 1-(3-chloro-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-(2-methoxyethyl)urea (214 mg, 0.794 mmol, 25.6% yield). MS ESI calc'd. for C10H13ClN5O2 [M+H]+ 270, found 270. was degassed THF (0.5 mL) was added The reaction was diluted with ethyl acetate washed with water The combined organics were dried over magnesium sulfate concentrated under reduced pressure The residue was purified by MPLC (0-30% MeOH-DCM)

实验步骤: 6-Chloro-3-(4-fluorophenyl)-1H-pyrazolo[4,3-c]pyridine (433 mg, 1.748 mmol), 1-(2-methoxyethyl)urea (313 mg, 2.65 mmol) and chloro[2-(dicyclohexylphosphino)-3,6-dimethoxy-2′-4′-6′-tri-i-propyl-1,1′-biphenyl][2-(2-aminoethyl)phenyl]palladium(II) (97 mg, 0.121 mmol) were taken up in THF (10.5 mL) in a 20 mL microwave vial. 1 M potassium t-butoxide in THF (5.25 mL, 5.25 mmol) was added and the vial was evacuated and back-filled with N2 (x3). The reaction mixture was stirred at 60° C. for 18 hours. Room temperature was attained and the mixture filtered through Celite, eluting with MeOH. The filtrate was concentrated in vacuo and the residue purified by MPLC (0-10% MeOH-EtOAc). The product was then triturated in EtOH to give 1-(3-(4-fluorophenyl)-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-(2-methoxyethyl)urea (237 mg, 0.720 mmol, 41.2% yield). MS ESI calc'd. for C16H17FN5O2 [M+H]+ 330, found 330. 1H NMR (600 MHz, DMSO-d6) δ 13.21 (s, 1H), 9.15 (s, 1H), 9.04 (s, 1H), 8.07-8.04 (m, 2H), 7.72 (s, 1H), 7.35-7.31 (m, 3H), 3.39 (t, J=5.5 Hz, 2H), 3.32-3.29 (m, 2H), 3.27 (s, 3H). the vial was evacuated back-filled with N2 (x3) Room temperature the mixture filtered through Celite eluting with MeOH The filtrate was concentrated in vacuo the residue purified by MPLC (0-10% MeOH-EtOAc) The product was then triturated in EtOH
