Stir the resulting mixture at ambient temperature for 72 h. Dilute the reaction mixture to 50 mL with CH2Cl2, wash with H2O, 1N NaOH, and brine sequentially. Dry the organic layer (MgSO4), filter and evaporate to give 0.189 g of crude product. Chromatograph on the ISCO using a 12 g column and eluting with Hexane-EtOAc (0-100%) to gives the title compound 0.60 g as a foam:
