Procedure
To 4-chloro-3-methoxy-10-methyl-10H-phenothiazine (0.5 g)(see Example 5) was added acetic acid (12 ml) and hydrogen peroxide (2 ml). The reaction mixture was heated at 50° C. for 15 minutes and then, evaporated to dryness. The corresponding sulfoxide (0.5 g) (4-chloro-3-methoxy-10-methyl-5-oxo-10H-phenothiazine) was obtained by crystallization (m.p. decomposed at 141° C.).
