実験手順
Dissolve 2-(methanesulfonyl-methylamino)-6-(methylpropylamino)-isonicotinic acid methyl ester (796 mg, 2.52 mmoles) in THF (35 mL) and add 1 N lithium hydroxide (12.6 mL). Stir at room temperature for 16 h, acidify with 5 N HCl (2.6 mL), and partition between diethyl ether and water. Wash the diethyl ether layer with saturated aqueous sodium chloride, dry (magnesium sulfate) and concentrate to give the title compound as a yellow solid (650 mg, 85%).
