Participants

Reaction Steps

Methanesulfonyl chloride (0.193 mL) is added to a solution of N-(4-chloro-benzyl)-6-(hydroxymethyl)-1-methyl-4-oxo-1,4-dihydro-3-quinolinecarboxamide (357 mg) from Example No. 2, DMAP (20 mg), and 2,4,6-collidine (0.33 mL) in anhydrous DMF (20 mL). The mixture is stirred at room temperate for 2 h, and poured into water (60 mL). The resulting percipitate is filtered, washed with water (20 mL), and recrystallized from acetonitrile to afford 0.328 g (74%) of the title compound as a white solid.
