The dichloromethane layer was dried (Na2SO4) and concentrated in vacuo to give a gum which was purified by column chromatography on silica eluting with hexane containing dichloromethane (25% up to 40%) and then with dichloromethane containing methanol (0% up to 5%). The product-containing fractions were combined and concentrated in vacuo to give the title compound as a gum yield, 0.25 g.
