Water (30 ml) was carefully added, then the mixture was extracted with ethyl acetate (2×25 ml). The combined extracts were washed with water (30 ml), dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by silica (1.5 g) column chromatography eluting with 80:20:1 ethyl acetate:hexane:ammonia solution (0.880). Product-containing fractions were combined and concentrated in vacuo to give the title compound as a pale yellow oil (14 mg, 38%).
