Lithium Hydroxide → 3-[1-(4-Chloro-phenyl)-piperidin-4-yl]-propionic acid lithium salt

Participants

Reaction Steps

To 3-[1-(4-chloro-phenyl)-piperidin-4-yl]-propionic acid methyl ester (345 mg; 1.22 mmol, prepared in accordance with Example 142) is added lithium hydroxide (72 mg; 3.00 mmol) dissolved in water (6.5 mL). After dilution with tetrahydrofuran (10 mL) the reaction mixture is stirred for 2-4 hours. The mixture is then diluted with acetonitrile until a precipitate is formed. The solid is collected by filtration and dried under high vacuum to deliver the desired product (300 mg; 1.10 mmol).
