Versuchsvorschrift

A flask was charged with (2S,4S)—N-(4-(4-fluorophenoxy)phenyl)-4-(thien-2-ylmethyl)pyrrolidine-2-carboxamide (84 mg, 0.21 mmol), 2-(2H-1,2,3-triazol-2-yl)acetic acid (29 mg, 0.23 mmol), DIEA (0.5 mL, 2.9 mmol), HATU (81 mg, 0.21 mmol) and DMF (3 mL). The reaction mixture was stirred at ambient temperature for 20 minutes and quenched with saturated sodium bicarbonate (aq., 10 mL). The mixture was extracted with ethyl acetate (20 mL) and the extract was washed with deionized water (10 mL) and then brine (10 mL), dried over anhydrous sodium sulfate, filtered and concentrated. Product was purified from the residue by reverse phase HPLC to give Compound 64, (2S,4S)-1-(2-(2H-1,2,3-triazol-2-yl)acetyl)-N-(4-(4-fluorophenoxy)phenyl)-4-(thien-2-ylmethyl)pyrrolidine-2-carboxamide (6.1 mg, 0.012 mmol, 6% yield), as an off-white solid. 1H-NMR (400 MHz, CDCl3): 9.15 (s, 1H), 7.72 (s, 2H), 7.44 (d, J=8.8 Hz, 2H), 7.18-7.16 (m, 1H), 7.03-6.82 (m, 8H), 5.29 (s, 2H), 4.86 (d, J=8.0 Hz), 3.63-3.58 (m, 1H), 3.25-3.20 (m, 1H), 3.12 (dd, J=13.6, 4.8 Hz, 1H), 3.01-2.87 (m, 2H), 2.73 (dd, J=12.4, 5.2 Hz, 1H), 1.75-1.68 (m, 1H). MS (EI) for C26H24FN5O3S. found 506.2 (MH+).
