实验步骤: Lithium hydroxide (2 N, 250 ml) is added to a mixture of 4-hydroxymethyl-bicyclo[2.2.2]octane-1-carboxylic acid methyl ester (XVI, Example 91) in a mixture of THF (50 ml) and methanol (75 ml). The resulting reaction mixture is stirred at 20-25° for 16 hr, and then concentrated. The residue is diluted with water (30 ml) and washed with methylene chloride (100 ml) and ethyl acetate (100 ml). The aqueous layer is acidified with concentrated hydrochloric acid pH about 0 and extracted with ethyl acetate (3×250 ml). The ethyl acetate layers are combined and washed with saline (3×50 ml), dried over anhydrous sodium sulfate and concentrated to give the title compound, NMR (400 MHz, CDCl3) δ 3.09, 1.72 and 1.29. The resulting reaction mixture concentrated The residue is diluted with water (30 ml) washed with methylene chloride (100 ml) and ethyl acetate (100 ml) extracted with ethyl acetate (3×250 ml) washed with saline (3×50 ml) dried over anhydrous sodium sulfate concentrated
