By a procedure similar to that of Example 17, the reaction of 11-methylene-3-methylthio-11H-s-triazolo[3,4-b][3]benzazepine with m-chloroperbenzoic acid gave 11-methylene-3-methylsulfinyl-11H-s-triazolo[3,4-b][3]benzazepine as crystals. Recrystallization from ethyl acetate yielded colorless prisms, m.p. 140°-142° C.
