实验过程

2,2-Dimethyl-propionic acid (3RS,4RS)-3-methyl-piperidin-4-yl ester (5) (9.6 g, 48 mmol) is dissolved in 50 ml of ethyl acetate. A solution of (−)-dibenzoyltartrate (8.6 g, 24 mmol) in ethyl acetate is added drop wise. The precipitate is filtrated off and washed with cold ethyl acetate to yield colourless crystals.
