Procedure

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 (0.06 mL, 0.5 mmol) in CH2Cl2 (3.0 mL) was added isonicotinoyl chloride hydrochloride (56 mg, 0.32 mmol). The reaction was stirred at rt for 18 h and then was poured into a mixture of EtOAc and sat. aq. NaHCO3. The organic solution was separated and washed with brine, dried over MgSO4, and concentrated to an oily residue. The residue was purified on a BIOTAGE® 10M (eluted with 80% EtOAc/hexanes) to give a white solid (36 mg, 30%). MS (ESI), (M+H)+509.20; 1H NMR (CDCl3, 500 MHz) δ 8.66 (br s, 2H), 7.80 (d, 1H, J=8.6), 7.73 (d, 2H, J=8.5), 7.51 (d, 2H, J=7.6), 7.41 (br s, 1H), 6.64 (br s, 1H), 5.35 (br s, 1H), 4.70 (br s, 1H), 4.10 (br s, 1H), 3.71 (br s, 1H), 3.33 (br s, 1H), 3.02 (dd, 2H, J=4.8, 16), 2.70-2.85 (br s, 1H), 1.50-2.09 (m, 5H), 1.18-1.33 (m, 4H), 0.73 (d, 3H, J=6.7), 0.68 (d, 3H, J=6.5).
