Reaction Steps

5-(2-(3-cyclopentenylphenyl)pyridin-3-yl)-1H-pyrazolo[3,4-b]pyridine (130 mg) was hydrogenated with Pd/C (15 mg) in EtOH (15 mL) over a period of 10 h under balloon H2 after degassing and back filling the flask with the hydrogen. The reaction mixture was filtered through celite and purified by preparative HPLC to provide 5-(2-(3-cyclopentylphenyl)pyridin-3-yl)-1H-pyrazolo[3,4-b]pyridine as a white solid. 1H NMR (DMSO-d6): δ 8.84 (d, 1H, J=4.7 Hz), 8.41 (d, 1H, J=7.9 Hz), 8.16 (app s, 2H), 8.14 (app s, 1H), 7.89 (app t, 1H, J=7.5 Hz), 7.23 (app s, 2H), 7.22-7.20 (m, 1H), 7.08 (s, 1H), 2.80 (q, 1H, J=8.2 Hz), 1.75-1.68 (m, 2H), 1.48-1.39 (m, 4H), 1.17-1.07 (m, 2H).LCMS: rt 5.13 min (A), purity 97%, MS (m/e) 341 (MH+).
