Sodium Hydroxide → N-[4-[(dipropylamino)methyl]phenyl]-4-[[1H-imidazol-2-ylmethyl(3-isoquinolylmethyl)amino]methyl]benzamide

Participants

Reaction Steps

The compound (53.9 mg) obtained in Example 47-3 was dissolved in methanol (2.0 ml) and then added with the compound (20.2 mg) obtained in Example 47-1 and sodium cyanoborohydride (12.8 mg). Then, the solution was adjusted to pH 5 with acetic acid and then stirred at room temperature for 14 hours. After completion of the reaction, a 1 mol/l sodium hydroxide aqueous solution was added to the reaction solution, followed by separation/extraction with chloroform. The organic layer was dried with anhydrous sodium sulfate and the solvent was then distilled off. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate) and then treated with hydrochloric acid, thereby obtaining hydrochloride (10.1 mg) of the subject compound as a white solid.
