Participants

Reaction Steps

To a suspension of sodium thiomethoxide (230 mg, 3.2 mM) in dimethylformamide (20 mL), was added in one portion 2-(2-bromoethyl)-7-chloro-4-hydroxy-1,2,5,10-tetrahydropyridazino[4,5-b]quinoline-1,10-dione (0.4 g, 1.08 mM) as a dry powder. This mixture was warmed to gentle reflux for about three hours. At this point the heat was removed and the reaction mixture was poured into ice cold 1.2N HCl (100 mL) and stirred about one hour. The resulting precipitate was vacuum filtered and washed with water and ether, then vacuum dried at 50° C. to yield 330 mg (91 %) of the title compound as an off-white powder. mp 275-277° C.; MS: 338(M+1).
