実験手順

Hydrogen chloride gas was bubbled into a suspension of 4′-[(5-hydroxy-4-hydroxymethyl-6-methyl-pyridin-3-ylmethyl)-amino]-biphenyl-2-sulfonic acid tert-butylamide (2) (160 mg, 0.36 mmol) in methyl alcohol (20 mL) at 0° C. for 10 minutes. The solvent was evaporated and the products were purified on a silica gel column using a mixture of methyl alcohol:dichloromethane (1:9) as eluant to give 4′-[(5-hydroxy-4-hydroxymethyl-6-methyl-pyridin-3-ylmethyl)-amino]-biphenyl-2-sulfonic acid amide (3) (139 mg, 25% yield).
