The reaction mixture was filtered through a disposable fritted funnel. The filter cake was washed with EtOAc. Layers in the filtrate were separated and the aqueous phase was extracted with EtOAc (3×). The organic phases were combined, dried over Na2SO4, filtered, concentrated, and further dried under high vacuum to afford the title compound as a brown solid (49 mg, 0.206 mmol, 77% yield). ESI MS (M+H)+=227.1.
