실험 절차
Hydrazine monohydrate (11.3 ml) was added to a solution of 4-amino-5-chloro-N-(1-(5-(2,3-dihydro-1,3-dioxo-1 H-isoindol-2-yl)pentyl)-piperidin-4-ylmethyl)-2-methoxybenzamide (60 g) in ethanol (0.6 L), and the mixture was refluxed under heating for 4 hr. The precipitated crystals were filtered off, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform:methanol=10:1) to give 37.0 g of 4-amino-N-(1-(5-aminopentyl)piperidin-4-ylmethyl) -5-chloro-2-methoxybenzamide.
