2-(2-Bromoethyl)-7-chloro-4-hydroxy-1,2,5,10-tetrahydropyridazino[4,5-b]quin-oline-1,10-dione (1.00 g, 2.7 mM, prepared in Example 4a. and p-anisidine(1.33 g, 10.8 mM) were stirred and heated to reflux in DMF (20 mL) for 1.5 hours to give a brown solution. The solution was cooled to room temperature and ether (80 mL) was added to give a dark suspension. The suspension was stirred for two hours and filtered. The collected solids were washed with ether (150 mL) to give the title compound as a tan powder(1.17 g, 60%), mp 239°-241° C.; MS(CI): 413.
