実験手順
To 3-[1-(4-tert-butyl-phenyl)-piperidin-4-yl]-propionic acid methyl ester (295 mg; 0.97 mmol, prepared in accordance with Example 145) 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 (468 mg) which is used in the next step without further purification.
