Participants

Reaction Steps

To a solution of 8-chloro-2-(2-(isopropylmethylamino)ethyl)-5-methyl-2H(1)benzothiopyrano[4,3,2-cd]indazole (0.19 g.) in acetone (3 ml.) was added 0.25 ml. of 30% aqueous hydrogen peroxide and the mixture was kept at room temperature for 4 days. The solid obtained on evaporation of the solution under reduced pressure was crystallized from ethanol-ether to give 8-chloro-2-(2 -(isopropylmethylamino)ethyl)-5-methyl-2H(1)benzothiopyrano[4,3,2-cd]indazole N-oxide monohydrate, m.p. 132°-133° (decomp.).
