Participants

Reaction Steps

Under nitrogen, to a solution of the product of Step 2 (31 mg, 85 μmol) in DMF (2 mL), was added [2-(4-morpholinyl)ethyl]amine (23 mg, 170 mmol), HOBT (35 mg, 0.26 mmol), HBTU (49 mg, 0.13 mmol), followed with 4-methylmorpholine (30 μL, 0.26 mmol). This mixture was then stirred at rt for overnight. The reaction mixture was concentrated, residue was purified with reverse phase HPLC (10% MeCN/H2O→80% MeCN/H2O, containing 0.1% TFA), to afford the title compound as a pale yellow solid (53 mg, 90%). %). 1H NMR (400 MHz, DMSO) δ ppm 9.74 (t, 1H, 4.4 Hz), 9.28 (s, 1H), 8.73 (t, 1H, 5.2 Hz), 8.16 (s, 1H), 7.87 (s, 1H), 7.73 (d, 1H, 8.0 Hz), 7.56 (d, 1H, 7.2 Hz), 7.49 (d, 1H, 7.6 Hz), 6.96 (s, 2H), 4.72 (q, 2H, 7.2 Hz), 4.41 (s, 2H), 4.00 (d, 2H, 11.2 Hz), 3.53-3.68 (m, 6H), 3.30 (bs, 2H), 3.14-3.17 (m, 2H), 1.42 (t, 3H, 7.2 Hz). MS (ES+) m/e 477 [M+H]+.
