Versuchsvorschrift

4-Amino-5-chloro-2-methoxy-N-(piperidin-4-ylmethyl)benzamide hydrochloride (15.0 g) was dissolved in dimethylformamide (100 ml) and toluene (150 ml). Potassium carbonate (18.6 g) and 4-bromobutylphthalimide (12.7 g) were added, and the mixture was stirred at 70 ° C. for 2 hr. The reaction mixture was concentrated under reduced pressure and the residue was extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography to give 13.6 g of 4-amino-5-chloro-N-(1-(4-(2,3-dihydro-1,3-dioxo-1H-isoindol-2-yl)butyl)-piperidin-4-ylmethyl)-2-methoxybenzamide.
