실험 절차

A solution of LiOH.H2O (5.1 g, 120 mmol) in 130 ml of water is added dropwise at 0° C. to a solution of the compound from Example VIII (13.1 g, 54.5 mmol) in 70 ml of THF. The solution is stirred at room temperature for 20 h, the THF is stripped off in vacuo and the residue is extracted once with 40 ml of ether. The aqueous phase is brought to pH 2 with 10% strength hydrochloric acid and extracted three times with 200 ml of ethyl acetate each time. The combined ethyl acetate phases are dried over Na2SO4 and the solvent is stripped off in vacuo.
