Versuchsvorschrift

4-(4-(2-methyl-5-((2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(methylthio)tetrahydro-2H-pyran-2-yl)benzyl)phenoxy)butanoic acid (39, 46 mg, 0.10 mmol), 1-aminocyclopentanecarboxamide (26 mg, 0.20 mmol), HATU (57 mg, 0.15 mmol), and DIPEA (52 μL, 0.30 mmol) were combined in DMF (0.5 mL) and stirred overnight at room temperature. The reaction was diluted with EtOAc, washed with saturated aqueous NaHCO3 and brine (with back extraction), dried over MgSO4, filtered, and concentrated under vacuum. The material was purified by prep HPLC (C18 30×100 mm column, 20-60% CH3CN/10 mM aqueous ammonium formate, 45 mL/min) and lyophilized to give 35 mg (61% yield) of amide 41 as a white solid. 1H NMR (400 MHz, MeOH-d4) δ ppm 7.10-7.19 (m, 3 H), 7.04 (d, J=8.6 Hz, 2 H), 6.81 (m, J=8.6 Hz, 2 H), 4.39 (d, J=9.3 Hz, 1 H), 4.12 (d, J=9.1 Hz, 1 H), 3.96 (t, J=6.2 Hz, 2 H), 3.92 (s, 2 H), 3.34-3.50 (m, 3 H), 2.41 (t, J=7.5 Hz, 2 H), 2.12-2.22 (m, 8 H), 2.04 (quin, J=6.9 Hz, 2 H), 1.93 (dt, J=12.8, 5.1 Hz, 2 H), 1.64-1.75 (m, 4H); MS (ES+) [M+H]+=573.
