実験手順
A suspension of N-(4-chlorobenzyl)-4-hydroxy-6-iodo-3-quinolinecarboxamide (2.0 g) of Preparation No. 4 and of potassium carbonate (2.0 g) in DMF (40 mL) is stirred at room temperature for 5 hrs and then treated with of O-(mesitylsulfonyl)hydroxylamine (1.5 g). After 24 hrs, the solvent is evaporated under reduced pressure and the residue is diluted with water(150 mL). The resulting solid is filtered and washed with water (3×) and ether (2×). Recrystallization from hot acetic acid/water affords 1.35 g of the title compound as a tan solid.
