Procedure

To a solution of 2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid (prepared as in Example 3, 200 mg, 0.48 mmol) and morpholine (51 μL, 0.58 mmol) in dichloromethane (1 mL), N,N-dimethylformamide (500 μL) and N-methylmorpholine (152 μL, 1.45 mmol) was added 1-hydroxybenzotriazole hydrate (132 mg, 0.97 mmol) followed by N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (186 mg, 0.97 mmol) in one portion. The mixture was then stirred at 25° C. for 14 h. The mixture was diluted with ethyl acetate (100 mL), washed with a 1 N aqueous sodium bicarbonate solution, 1 N aqueous hydrochloric acid solution, brine, dried over anhydrous sodium sulfate and then 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 {2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-morpholin-4-yl-methanone (85 mg, 36%) as a yellow solid: LC/MS m/e calcd for C26H31N3O4S [M+H]+ 482.62, observed 482.2; 1H NMR (400 MHz, CDCl3) δ ppm 1.17 (m, 2H), 1.47 (m, 2H), 1.55-1.85 (m, 5H, H), 2.09 (m, 1H), 2.25 (m, 1H), 3.02 (s, 3H), 3.72 (br. s., 8H), 4.27 (t, J=7.9 Hz, 1H), 6.41 (s, 1H), 7.46 (d, J=8.4 Hz, 2H), 7.83 (d, J=8.4 Hz, 2H), 7.93 (d, J=1.9 Hz, 1H), 8.20 (d, J=1.9 Hz, 1H), 11.01 (br, 1H).
