Participants

Reaction Steps

To a solution of Example 4 (16.0 mg, 26 μmol), 4-dimethylaminopyridine (0.6 mg, 5.2 μmol), and EDC hydrochloride (5.3 mg, 28 μmol) in DMF (0.5 mL) was added morpholine (2.3 μL, 26 μmol). The reaction mixture was stirred at RT overnight and then diluted with water (5.0 mL). The resulting solid was collected by filtration and purified by flash column chromatography, eluting with 0-7% methanol in DCM to afford the title compound, Example 5, (7.0 mg, 57%) as a yellow solid: m/z 689/691 (M+H)+ (ES+); Rt 3.54 min; 1H NMR (500 MHz, DMSO-d6) δ: 1.71 (2H, quin), 2.43-2.49 (2H, m), 2.52-2.55 (2H, m), 3.20-3.26 (2H, m), 3.28-3.33 (4H, m), 3.44 (2H, t), 5.28 (2H, s), 5.72 (2H, s), 6.17 (1H, d), 6.78 (1H, t), 6.87 (2H, d), 7.02 (1H, t), 7.10 (1H, d), 7.32 (2H, d), 7.60 (1H, d), 7.67 (1H, d), 7.79 (1H, t), 8.16 (1H, s), 9.75 (1H, s).
