Diisopropylazodicarboxylate (0.017ml, 0.088mmoles, 1.1eq) was then added dropwise and the reaction was stirred for 2hours at room temperature. The reaction was then partitioned between EtOAc and H2O. After the separation of the phases the organic phase washed with 0.1N NaOH, brine, dried over Na2SO4, filtered, concentrated in vacuo and purified via flash chromatography (10% EtOAc/Hexanes to 35% EtOAc/Hexanes) to yield 40mg (76%) of product.
