実験手順
847 mg (2.43 mmol) of ethyl 4-(1-t-butoxycarbonyl-4-piperidyloxy)benzoate was dissolved in 50 ml of ethanol. 5 ml of 1 N sodium hydroxide solution was added to the solution, and they were stirred at room temperature for 3 days. The reaction liquid was concentrated, and the title compound was obtained by the same isolation process as that of step 1 in Example 1 with ethyl acetate as the extractant.
