Versuchsvorschrift

To a solution of 4-[2-{(2R)-2-[(1E,3S)-3-hydroxy-oct-1-enyl]-5-oxopyrrolidin-1-yl}ethyl)benzoic acid (71.90 mg, 0.2 mmol) in DMF (1 mL) was added EDC (57.51 mg, 0.3 mmol), HOBt (40.54 mg, 0.3 mmol), ammonia chloride (21.40 mg, 0.4 mmoL) and DIPEA. The mixture was stirred for overnight. After evaporation of the solvent, the residue was purified through RP-HPLC using ACN and H2O/0.1% TFA to afford the desired product (70 mg) as a white solid. 1HNMR (CD3OD, ppm) δ 0.879 (m, 3H), 2.297 (br, 6H), 1.49 (m, 2H), 1.75 (m, 1H), 2.19 (m, 1H), 2.34 (m, 2H), 2.89 (m, 2H), 3.17 (m, 1H), 3.73 (t, J=7.0 Hz, 1H), 4.04 (t, J=6.2 Hz, 2H), 5.45 (dd, J=8.8 and 15.1 Hz, 1H), 5.66 (dd, J=6.6 and 15.1 Hz, 1H), 7.30 (d, J=7.7 Hz, 2H), 7.82 (d, J=7.7 Hz, 2H), (m/z): 381.4 (+Na+).
