Summary:PROBLEM TO BE SOLVED: To provide a method for preparing quarternary salts from mandelic acid piperidyl esters.SOLUTION: The present invention provides a method of reacting a compound represented by formula (II) with an alkylating agent represented by formula (III) to convert piperidyl esters represented by formula (II) to quarternary salts. In the formula (II), Rand Rindependently represent H, an alkyl group or an aryl group, and in the formula (III): RX, X is halogen atom and Ris H, an alkyl group or an aryl group. 【課題】マンデル酸のピペリジルエステルの第４級塩を調製する方法を提供する。【解決手段】式（ＩＩ）で表される化合物を式（ＩＩＩ）で表されるアルキル化剤と反応させることで式（ＩＩ）で表されるピペリジルエステルを第４級塩に変換する方法。（Ｒ１及びＲ２は各々独立にＨ、アルキル基又はアリール基）Ｒ３Ｘ（ＩＩＩ）（Ｘはハロゲン原子；Ｒ３はＨ、アルキル基又はアリール基）【選択図】なし
