The material was filtered thru celite and concentrated, then partitioned between saturated sodium bicarbonate solution and methylene chloride, the organics were washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude material was purified via prep tic using ETOAc as the eluant to give the title compound (0.027 g, 54% yield).
