Procedure

A mixture of 3-{4-[2-cyclopentyl-1-(1H-pyrrolo[2,3-b]pyridin-2-yl)-vinyl]-phenyl}-pentan-3-ol (120 mg, 0.32 mmol) and 10% palladium on activated carbon (36 mg) in methanol (250 mL) was heated at 50° C. under hydrogen (50 psi) for 16 h. The mixture was cooled to 25° C., the solids filtered off, washed with ethyl acetate and concentrated in vacuo. Purification using a Waters automated flash system (column: Xterra 30 mm×100 mm, sample manager 2767, pump 2525, detector: ZQ mass and UV 2487, solvent system: acetonitrile and 0.1% ammonium hydroxide in water) afforded 3-{4-[2-cyclopentyl-1-(1H-pyrrolo[2,3-b]pyridin-2-yl)-ethyl]-phenyl}-pentan-3-ol (68 mg, 60%): LC/MS m/e calcd for C25H32N2O [M+H]+ 377.55, observed 377.3; 1H NMR (400 MHz, CD3OD) δ ppm 8.04 (d, J=3.8 Hz, 1H), 7.87 (dd, J=7.7, 1.1 Hz, 1H), 7.25-7.34 (m, 4H), 7.02 (dd, J=7.7, 4.9 Hz, 1H), 6.31 (s, 1H), 4.15 (t, J=7.8 Hz, 1H), 2.21 (dt, J=13.7, 7.2 Hz, 1H), 2.03-2.11 (m, 1H), 1.58-1.85 (m, 9H), 1.42-1.54 (m, 2H), 1.14-1.28 (m, 2H), 0.72 (td, J=7.4, 2.1 Hz, 6H).
