Procedure

This compound was prepared by diazotizing a solution of 18.5 g of 2'-amino-5'-methyl-2-(methylsulfinyl)acetophenone in 500 ml of 1N HCl with 6.3 g of NaNO2 in analogous fashion to 6-chloro-3-(methylsulfinyl)-4(1H)-cinnolinone. The material was recrystallized from DMF, m.p. 265°-67°; yield 15 g (77%).
