Procedure

Compound 310 (479 mg, 1.0 mmol), Acetyl chloride (100 mg, 1.2 mmol), DIPEA (260 mg, 2.0 mmol) was dissolved in THF (10 mL). The reaction mixture was stirred at r.t. for 1 hour. LC-MS indicated the reaction was completed. To the reaction mixture was added 20 mL of water, the mixture was extracted with dichloromethane. The organic layer was dried over anhydrous sodium sulfate, and concentrated to dryness. The crude was purified by pre-HPLC to afford 311 (78.1 mg, yield: 15%). 1HNMR (DMSO-d6, 400 MHz): δ8.27 (s, 1H) 7.91-7.90 (m, 1H), 7.74 (s, 1H), 7.43-7.39 (m, 1H), 7.23-7.20 (m, 2H), 6.48 (t, J=4.4 Hz, 1H), 4.77 (s, 2H), 3.53 (s, 2H), 3.53-3.32 (m, 4H), 3.19 (s, 2H), 1.96 (s, 3H), 1.23 (s, 2H).
