Procedure
A mixture of (IV) (9.4 g of crude oil, ca. 33 mmol) and Claisen's reagent (18 mL) were heated at 90–95° C. for 1 h. After cooling to room temperature, the solution was diluted with 15 g of crushed ice and acidified to pH 1–2 with 6 N HCl. The brown oily precipitate was dissolved in ether, washed with brine solution, dried over MgSO4, filtered and evaporated to waxy solids. Triteration of the solids with pentane afforded 6.6 g of V as a tan powder (84.7% yield).
