HPLC/MS (Method C) RT = 3.35 min, [M+H] 468; .H NMR (500 MHz, methanol-i/3) (delta ppm): 1.83-1.95 (m, 2 H), 2.66 (t, J=7.70 Hz, 2 H), 3.36 (t, J=6.87 Hz, 2 H), 3.85 (t, J=5.22 Hz, 2 H), 4.11-4.20 (m, 4 H), 6.91 (d, J=4.40 Hz, 1 H), 6.93 (d, J=3.85 Hz, 1 H), 6.99 (t, J=8.80 Hz, 2 H), 7.14 (dd, J=8.25, 2.20 Hz, 1 H), 7.35-7.41 (m, 2 H). | |
14% | Example 167. N-(3-(3,4-dichlorophenyl)propyl)-l-(2-(4-fluorophenoxy)ethyl)-4- h drox -5 -oxo-2,5 -dihydro- 1 H-pyrrole-3 -carboxamide[00219] To a solution of <strong>[6096-89-5]2-(4-fluorophenoxy)ethanamine</strong> (0.022 g, 0.14 mmol) in MeOH (3 mL) was added DIPEA (0.024 mL, 0.14 mmol). The mixture was stirred for 5 min at rt, then paraformaldehyde (4.19 mg, 0.140 mmol) was added. The mixture heated at 60 C for 10 min using microwave irradiation. The reaction was cooled to rt, then Intermediate 5 (50 mg, 0.140 mmol) was added in a single portion. The reaction mixture was heated at 100 C for 15 min using microwave irradiation, then stirred at rt for 16 h. The reaction mixture was diluted with MeOHiH^O (9: 1) containing 0.1 % TFA, then purified by RP preparative HPLC (Method C) to obtain 9.2 mg (14% yield) of Example 167. HPLC/MS (Method C) RT = 3.35 min, [M+H]+ 468; .H NMR (500 MHz, methanol-^) (delta ppm): 1.83-1.95 (m, 2 H), 2.66 (t, J=7.70 Hz, 2 H), 3.36 (t, J=6.87 Hz, 2 H), 3.85 (t, J=5.22 Hz, 2 H), 4.11-4.20 (m, 4 H), 6.91 (d, J=4.40 Hz, 1 H), 6.93 (d, J=3.85 Hz, 1 H), 6.99 (t, J=8.80 Hz, 2 H), 7.14 (dd, J=8.25, 2.20 Hz, 1 H), 7.35-7.41 (m, 2 H). |
