Reaction Steps
A solution of 10 g of 6,7-dimethoxy-3-(methylsulfinyl)-4(1H)-cinnolinone in 148 ml of 1 normal NaOH was treated with 14 g of (CH3)2SO4 with stirring. As the (CH3)2SO4 dissolved, the temperature rose to ca. 35° and a pasty precipitate formed. The mixture was stirred for 45 minutes and the precipitate was filtered off, washed with cold H2O and recrystallized from CH3CN, mp. 262°-64°; yield 6 g (57%).
