The brown reaction mixture was cooled, diluted with EtOAc and washed with saturated NaHCO3. The aqueous layer was extracted with EtOAc (2*) and the combined organic extracts were washed with brine, dried (Na2SO4) and evaporated in vacuo. The residue was chromatographed (silica gel, EtOAc as eluent) to afford the title compound as a white solid. 1H NMR (400 MHz, CD3OD) delta 7.74 (d,J=2.7 Hz, 1H), 7.59 (dd, J=3.0 and 9.6 Hz, 1H), 7.51 (d, J=8.6 Hz, 2H), 7.37 (d, J=8.4 Hz, 2H), 6.61 (d, J=9.4 Hz, 1H) and 4.67(s,1H) ppm.

The mixture was cooled to room temperature, and then water (250 mL) was added to the mixture and the mixture was extracted with ethyl acetate (100 mL × 3). All the organic phases were mixed, sequentially rinsed with water (100 mL × 3) and a saline solution (100 mL × 1), dried (Na2SO4), filtered, and concentrated under reduced pressure. The residue was purified by flash column chromatography (60 g of silica gel, n-hexane/EtOAc = 5/1) to obtain Compound (14) as a colorless solid.
