Participants

Reaction Steps

To a solution of cis/trans-4-(pyrimidin-2-yloxy)-cyclohexanecarboxylic acid ethyl ester (1:2) (0.35 g, 1.4 mmol) in 1,4-dioxan (7 ml) was added 2 M aqueous sodium hydroxide solution (7.0 ml, 14 mmol). Stirring at room temperature for 16 h was followed by acidification to pH 2-3 with 0.5 M aqueous hydrogen chloride solution (50 ml) and extraction with three 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 (0.26 g, 83%) as yellow oil.
