Procedure
Method 2) A solution of 110 g of [4-[2-[2-hydroxy-5-(N-hydroxycarbamimidoyl)benzenesulfonylamino]ethyl]-2′-methanesulfonylbiphenyl-3-yloxy]acetic acid in 1.00 L of 14% hydrogen chloride n-butanol solution was stirred at 100° C. for 2.5 hours. The reaction mixture was concentrated under reduced pressure, and the residue was washed with ethyl acetate to give 111 g of crude crystal. The crude crystal was recrystallized from n-butanol-diisopropyl ether to give 83.3 g of n-butyl [4-[2-[2-hydroxy-5-(N-hydroxycarbamimidoyl)benzenesulfonylamino]ethyl]-2′-methanesulfonylbiphenyl-3-yloxy]acetate hydrochloride.
