실험 절차

To a solution of (2R)-2-[N-(4-chlorobenzenesulfonyl)-N-(piperidin-4-ylmethyl)amino]-4-methyl-pentanoic acid amide (Example 126, 0.050 g, 0.12 mmol) and Et3N (0.040 mL, 0.30 mmol) in CH2Cl2 (2.0 mL) was added 4-(2-chloro-acetyl)-benzonitrile (55 mg, 0.30 mmol). The reaction was stirred at rt for 18 h and then was concentrated to residue. The residue was purified on a Biotage system (eluted with 80% EtOAc/hexanes) to produce 29 mg (48%) of the desired product as a white solid. MS (ESI), (M+H)+ 545.16; 1H NMR (CDCl3, 500 MHz) δ 7.72 (d, 2H, J=8.5), 7.50-7.65 (m, 2H), 7.50 (d, 2H, J=7.0), 7.35-7.45 (m, 2H), 6.67 (s, 1H), 5.32 (s, 1H), 4.14 (dd, 1H, J=5.0, 9.0), 3.52 (br s, 1H), 3.28 (t, 1H, J=14), 2.97 (dd, 1H, J=3.5, 14), 2.82 (br s, 1H), 1.00-2.00 (m, 10H), 0.71 (d, 3H, J=6.5), 0.66 (d, 3H, J=6.5).
