By a procedure similar to that described in Examples 13, the reaction of 8-methyl-3-methylthio-11H-s-triazolo[3,4-b][3]benzazepine with selenium dioxide gave 8-methyl-3-methylthio-11H-s-triazolo[3,4-b][3]benzazepin-11-one as crystals. Recrystallization from methanol yielded colorless platelets melting at 178°-179° C.
