Pyridinium sulfate (4.351 g, 27.3 mmol) was added and the reaction stirred 0° C. for 1 hour. The reaction was poured onto 50 mL water and extracted with ethyl acetate. The combined organics were then dried over MgSO4, then concentrated in vacuo affording a yellow/white semi-solid, which was further purified by triturating with 20% ethyl acetate/Hexanes, affording the desired product as a tan solid (1.35 g, 68% yield).
