The reaction mixture was stirred at 0° C. for 1 hour and then at room temperature for 18 hours. The reaction mixture was quenched with sodium hydroxide (0.2M) until pH 11 obtained then extracted with DCM. The organics were filtered through a hydrophobic frit and concentrated in vacuo. The crude material was purified by SCX chromatography (2M ammonia in methanol) to afford the title compound.
