実験手順

A solution of aqueous 2N NaOH (2.00 ml) is added to a stirred solution of methyl 3-(2-(4-hydroxypiperidin-1-yl)quinoline-4-carboxamido)-2,4-dimethylbenzoate (0.10 g, 0.00023 mol) in THF:MeOH (4 ml:2 ml). After 5 h at 50° C., the organic solvent is removed under reduced pressure and the residue is diluted with water, acidified to pH 6 with aqueous 1N HCl, and extracted with ethyl acetate (2×20 ml). The organic layers are combined and dried over anhydrous sodium sulfate. The solvent is removed under reduced pressure and the resulting precipitate is triturated with pentane and diethyl ether and filtered to afford the title compound as a light yellow solid (0.03 g, 31%). Mass spectrum (m/z): 420.2 (M+1).
