The mixture was stir at 100 °C for 2 hr under nitrogen protection. Remove most organic solvent in vacuum, then the residue was re-dissolved in DCM, washed with water; the organic layer was dried over magnesium sulfate, filtered and concentrated in vacuum. The residue was purified by CombiFlash, eluted with methanol in DCM (0-5percent, 30 min). Collected the desired fraction to afford 40 mg brown syrup, it was further purified by basic Prep-HPLC (0.1 percent NH4OH/ACN/H20).Collected the desired fraction and lyophilized to afford 10 mg title compound as off-white powder. 1 H NMR (400 MHz, Methanol-^) delta 8.22 - 8.05 (m, 3H), 7.96 (d, J= 15.9 Hz, 1 H), 7.87 (s, 2H), 7.79 - 7.71 (m, 2H), 7.65 (d, J = 0.9 Hz, 1 H), 2.63 (d, J= 0.8 Hz, 3H).
