Procedure

To a solution of Example 260H (150 mg, 0.352 mmol) in N,N-dimethylformamide (1.8 mL) was added N-ethyl-N-isopropylpropan-2-amine (227 mg, 1.759 mmol) and 2-chloro-N,N-dimethylacetamide (39.9 μL, 0.387 mmol). The mixture was stirred for 3 days at room temperature and for 2 hours at 70° C., and partitioned between water and ethyl acetate (three times). The extracts were dried over sodium sulfate, filtered, and concentrated, and the residue was purified by flash chromatography on silica gel, eluting with a gradient of 0-8% methanol/dichloromethane to afford the title compound. 1H NMR (400 MHz, DMSO-d6) δ 11.77 (s, 1H), 8.18 (d, J=5.0 Hz, 1H), 7.31-7.16 (m, 3H), 7.02 (d, J=5.0 Hz, 1H), 6.46 (s, 1H), 6.18 (d, J=1.8 Hz, 1H), 4.61 (t, J=5.3 Hz, 1H), 3.74 (s, 3H), 3.60-3.27 (m, 6H), 3.33 (s, 3H), 3.02 (s, 3H), 2.93 (dd, J=11.1, 5.7 Hz, 1H), 2.81 (s, 3H), 2.48-2.32 (m, 2H); MS (ESI+) m/z 439.0 (M+H)+.
