The reaction was allowed to stir at this temperature for 2 h. The mixture was then poured into H2O and the desired product was extracted into ethyl acetate. The organic layer was backwashed once with H2O, dried over K2CO3, and concentrated under reduced vacuum to yield 256 mg as a foam. This material was purified via silica gel chromatography employing the Chromatotron, using a 4000 micron rotor and eluting with a solvent of hexane/ethyl acetate 1:1 to yield the title compound (130 mg, 56%) as a white foam. Ion spray M.S. 405.5 (M*−1).
