The added water and extracted 3 times with EtOAc. The organics were dried (MgSO4) and filtered off through a pad of Magnesol and concentrated in vacuo. to afford a solid. The solid was triturated with diethyl ether to give a white solid that was filtered and washed with diethyl ether to give (54 mg) MS m/z=476.2 (M+H).
