Procedure

To a solution of compound 7 (207 mg, 0.50 mmol) in DMF (5 mL) were added N,N-diisopropylethylamine (174 uL, 1.0 mmol) and acetyl chloride (43 uL, 0.60 mmol) in DMF (2 mL) at 0° C. and the resulted mixture was stirred at 0° C. for 1 hr. The reaction mixture was concentrated and the residue was washed with water (sonicated) and the solid was collected by filtration, dried under high vacuumn to give compound 186 (170 mg, 74% yield) as a light yellow solid. 1H NMR (500 MHz, DMSO-d6) δ 9.82 (1H, s), 9.27 (1H, s), 9.01 (1H, s), 8.44 (1 H, d, J=5 Hz), 8.21 (1H, d, J=10 Hz), 8.07 (1H, d, J=2 Hz), 8.04 (1H, d, J=5 Hz), 7.52 (1H, dd, J=10 Hz, J=2 Hz), 5.37 (1H, p, J=10 Hz), 3.61 (4H, q, J=5 Hz), 3.17 (2H, t, J=5 Hz), 3.10 (2H, t, J=5 Hz), (3H, s), 2.40 (2H, m), 2.08 (4H, m), 2.06 (3H, s), 1.78 (2H, m) ppm; LCMS-ESI (POS), M/Z, M+1: Found 456.1, Calculated 456.2.
