A mixture of (2-{2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-yloxy}-ethyl)-dimethyl-amine (200 mg, 0.44 mmol) and 10% palladium on activated carbon (40 mg) in methanol (200 mL) was heated at 50° C. under hydrogen (50 psi) for 6 h. The mixture was cooled to room temperature. The catalyst was removed by filtration and washed with ethyl acetate. The filtrate was concentrated in vacuo and purified 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) to afford (2-{2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-yloxy}-ethyl)-dimethyl-amine (20 mg, 10%) as a white solid: LC/MS m/e calcd for C25H33N3O3S [M+H]+ 456.62, observed 456.3; 1H NMR (400 MHz, CD3OD) δ ppm 1.26 (m, 2 H), 1.51 (m, 2H), 1.58-1.90 (m, 5H, H), 2.11 (m, 1H), 2.27 (m, 1H), 2.44 (s, 6H), 2.89 (t, J=5.4 Hz, 2H), 3.10 (s, 3H), 4.19 (t, J=5.4 Hz, 2H), 4.30 (t, J=8.0 Hz, 1H), 6.35 (s, 1H), 7.55 (d, J=2.8 Hz, 1H), 7.61 (d, J=8.3 Hz, 2H), 7.9 (m, 3H).
