Versuchsvorschrift

4-amino-5-chloro-N-(1-tert-butoxycarbonylpiperidin-4-ylmethyl)-2-methoxybenzamide (18.9 g) was dissolved in 4N hydrochloric acid-dioxane solution (150 ml). The mixture was stood at room temperature for 2 hr and the precipitated crystals were collected by filtration to give 15.3 g of 4-amino-5-chloro-2-methoxy-N-(piperidin-4-ylmethyl)-benzamide hydrochloride.
