Procedure
To a solution of cis/trans-4-(pyrimidin-4-yloxy)-cyclohexanecarboxylic acid ethyl ester (1:1) (0.90 g, 3.6 mmol) in 1,4-dioxane (18 ml) was added 2 M aqueous sodium hydroxide solution (18 ml, 36 mmol). Stirring at room temperature for 3 h was followed by acidification to pH 2-3 with 1 M aqueous hydrogen chloride solution (42 ml) and extraction with four 100-ml portions of ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo to give the title compound (0.76 g, 95%) as white solid.
