1 g of the product of step 1, above, in 35 ml of 100% ethanol is mixed with 0.4g of calcium carbonate (powdered) and 15 ml of water. The mixture is refluxed for about 4 hours, then cooled, quenched with water and extracted with ethyl acetate. The extracts are dried and then evaporated to dryness to yield a dark amber gum, which is chromatographed on prep. plates, using petroleum ether/ether (85/15) and the largest (second of three) major band eluted with ethyl acetate to obtain the title product of this example as yellow solids, mp 95°-101°.
