Versuchsvorschrift

A mixture of 5-fluoro-2-[(E)-1-(4-methanesulfonyl-phenyl)-2-(tetrahydro-pyran-4-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (prepared as in Example 122, 300 mg, 0.75 mmol) and 10% palladium on activated carbon (0.2 g) in methanol (50 mL) was heated at 45° C. under hydrogen (50 psi) for 5 h. After cooling to room temperature, the catalyst was removed by filtration and washed with ethyl acetate. The filtrate was concentrated in vacuo. The residue was 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 5-fluoro-2-[1-(4-methanesulfonyl-phenyl)-2-(tetrahydro-pyran-4-yl)-ethyl]-1H-pyrrolo[2,3-b]pyridine as a white solid (180 mg, 60%): LC/MS m/e calcd for C21H23FN2O3S [M+H]+ 403.49, observed 403.2; 1H NMR (400 MHz, CD3OD) δ ppm 8.01 (t, J=2.1 Hz, 1H), 7.91 (d, J=8.3 Hz, 2H), 7.60-7.67 (m, 3H), 6.41 (s, 1H), 4.44 (t, J=8.1 Hz, 1H), 3.90 (d, J=11.4 Hz, 2H), 3.25-3.30 (m, 2H), 3.08-3.14 (m, 3H), 2.24 (dt, J=14.1, 7.3 Hz, 1H), 1.99-2.07 (m, 1H), 1.72 (t, J=14.1 Hz, 2H), 1.32-1.52 (m, 3H).
