Procedure

3-{1-[(cis-4-Benzyloxycarbonyl-cyclohexyl)carbamoyl]cyclopentyl}-2-(2-ethoxyethyl)propanoic acid (225 mg, 0.476 mmole) was dissolved in 1,4-dioxan (20 ml), ethanol (4 ml) and water (6 ml) and was treated with 1N sodium hydroxide solution (2.4 ml, 2.4 mmole). After 20 hours at room temperature, the solution was evaporated to half volume, diluted with water (20 ml) and washed with diethyl ether. The aqueous layer was separated, acidified with 2N hydrochloric acid and extracted with ethyl acetate (3×20 ml). The ethyl acetate layer was separated, dried over magnesium sulphate and the solvent evaporated to give the title product as a colourless foam (161 mg, 88%). Found: C,61.89; H,8.29; N,3.62. C20H33NO6,0.2 H2O requires C,62.06; H,8.69; N,3.62%.
