Procedure

To (S)-2-{[(S)-1-(3-fluoro-benzenesulfonyl)-piperidine-2-carbonyl]-amino}-3-[4-(3-methoxy-propoxy)-phenyl]-propionic acid (98 mg, 0.19 mmol) in dichloromethane (3 mL) was added, a 2.0M methyl amine solution in THF (97 μL, 1.9 mmol), PyBoP (87 mg, 0.19 mmol) at room temperature. Upon reaction completion water was added. The mixture was extracted with ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated. The residue was chromatographed on silica gel (dichloromethane/ethyl acetate, 80/20 as eluant) to produce 35 (34%) mg of (S)-1-(3-fluoro-benzenesulfonyl)-piperidine-2-carboxylic acid {(S)-2-[4-(3-methoxy-propoxy)-phenyl]-1-methylcarbamoyl-ethyl}-amide. LC/MS rt=3.95, 536 m/e (M+H). 1H NMR (300 MHz, dmso-d6) 7.93 (d, J=8.2 Hz, 1H), 7.85 (m, 1H), 7.48-7.37 (m, 4H), 7.11 (d, J=8.3 Hz, 2H), 6.83 (d, J=8.5 Hz, 2H), 4.51 (d, J=4.5 Hz, 1H), 4.25 (m, 1H), 3.95 (t, J=6.5 Hz, 2H), 3.61 (m, 1H), 3.42 (t, J=6.2 Hz, 2H), 3.30-3.21 (m, 5H), 3.15 (m, 1H), 2.90-2.83 (m, 1H), 2.73-2.66 (m, 1H), 2.54 (d, J=4.8 Hz, 3H), 1.95-1.97 (m, 2H), 1.50-1.25 (m, 2H), 1.50-1.05 (m, 2H).
