Versuchsvorschrift

This was prepared by oxidizing a solution of 10 g of 7-chloro-1-methyl-3-(methylsulfinyl)-4(1H)-cinnolinone in 500 ml of CHCl3 with 7.5 g of m-chloroperbenzoic acid in analogous fashion to 1-methyl-3-(methylsulfonyl)-4(1H)-cinnolinone. The material was recrystallized from CH3CN, m.p. 270°-72°; yield 7.5 g (71%).
