Reaction Steps
This was prepared in analogous fashion to 6-chloro-3-(methylsulfinyl)-4(1H)-cinnolinone by diazotizing a suspension of 11 g of 2'-amino-4'-chloro-2-(methylsulfinyl) acetophenone in 250 ml of 1N HCl with 3.5 g of NaNO2. The material was recrystallized from dimethyl formamide m.p. 285°-90°; yield 10 g (87%).
