実験手順

To a solution of (2R)-2-[N-(4-chlorobenzenesulfonyl)-N-(piperidin-4-ylmethyl)amino]-4-methyl-pentanoic acid amide (Example 126, 0.10 g, 0.22 mmol) and Et3N (32 μL, 0.25 mmol) in CH2Cl2 (3.0 mL) was added (2-isocyanato-ethyl)-benzene (0.040 mL, 0.30 mmol). The reaction was stirred at rt for 18 h and then was poured into sat. aq. NaHCO3 and extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4, and concentrated to an oily residue. The residue was further purified on a Biotage system (eluted with 75% EtOAc/hexanes) to afford the desired product as a white solid (67 mg, 52%). MS (ESI), (M+H)+ 549.00; 1H NMR (CDCl3, 500 MHz) δ 7.71 (d, 2H, J=8.6), 7.71 (d, 2H, J=8.9), 7.15-7.35 (m, 5H), 6.64 (s, 1H), 5.86 (s, 1H), 4.15 (dd, 1H, J=5.2, 9.5), 3.88 (d, 1H, J=13), 3.76 (d, 1H, J=13), 3.46 (t, 2H, J=6.7), 3.21-3.29 (m, 1H), 2.97 (dd, 1H, J=4.6, 14), 2.65-2.85 (m, 4H), 1.75-1.95 (m, 3H), 1.00-1.30 (m, 5H), 0.75-0.80 (m, 1H), 0.72 (d, 3H, J=6.7), 0.67 (d, 3H, J=6.7).
