Procedure
(1S(1.Alpha.,2α,4α))-2-hydroxy-7,7-dimethyl-1-((spiro(1H-indene-1,4'-piperidin)-1'-yl sulfonyl)methyl)bicyclo(2.2.1)heptane-2-acetic acid ethyl ester (45 mg, 0.092 mmol) was stirred in a mixture of methanol (1 ml) and water (1 ml) and treated with sodium hxdroxide (0.1 ml of a 5N solution in water; 0.5 mmol). The mixture was stirred for 1 hr at ambient temperature, then evaporated to dryness in vacuo. The residue was treated with saturated sodium bicarbonate solution and extracted with ether. The ether layer was evaporated to dryness in vacuo and the residue was chromatographed on a silica gel column eluted with 15% EtOAc in hexane. The product fractions were evaporated to dryness in vacuo, and the residue was triturated with CH2Cl2 and again evaporated to dryness. The residue was dried in vacuo at ambient temperature overnight to give the title compound: (mp 81°-83°).
