Reaction Steps
To a solution of 3-[(R)-4-(6-chloro-pyridine-3-sulfonyl)-2-cyclohexyl-6-oxo-piperazin-1-yl]-5-phenyl-thiophene-2-carboxylic acid (100 mg, 0.18 mmol, 1.0 equiv) in DMF (0.8 mL) at room temperature was added pyrrolidine (127 mg, 1.79 mmol, 10.0 equiv) and Et3N (0.37 mL, 2.68 mmol, 15.0 equiv). The mixture was stirred at 70° C. for 2 hours. The mixture was then cooled to room temperature and filtered. The filtrate was concentrated and purified by HPLC (0.1% NH4OH) to give product (35 mg, 33%) as white solid. MS: 595 [M−H+]. 1H-NMR (400 MHZ, MeOD): δ 1.10-1.23 (m, 5H), 1.40-2.00 (m, 10H), 3.04-3.12 (m, 2H), 3.20 (t, 2H), 3.42 (d, 2H), 3.88 (d, 1H), 3.97 (br, 1H), 4.07 (d, 1H), 6.62 (s, 1H), 7.19 (s, 1H), 7.32 (t, 1H), 7.40 (t, 2H), 7.63 (d, 2H), 7.83 (m, 1H), 8.44 (d, 1H).
