実験手順
At room temperature, 3.0 ml of 4 M hydrogen chloride/1,4-dioxane was added to 8 ml of 1,4-dioxane solution containing 543 mg of ethyl 1-(2-tert-butyl-2-oxoethyl)piperidine-4-carboxylate, and stirred at 60° C. for 8Hours. The thus formed solid was collected by filtration to obtain 300 mg of [4-(ethoxycarbonyl)piperidin-1-yl]acetic acid as a white solid. EP: 216.
後処理
