실험 절차

To 1-[1-(tert-butoxycarbonyl)piperidin-4-ylmethyl]-4-(5-chlorobenzofuran-2-sulfonyl)-2-piperazinone (270 mg) were added 4N hydrochloric acid in ethyl acetate (8 ml) and methanol (2 ml), and the mixture was stirred at room temperature for 30 minutes. The reaction solution was concentrated to give 4-(5-chlorobenzofuran-2-sulfonyl)-1-(piperidin-4-ylmethyl)-2-piperazinone hydrochloride (229 mg).
