The reaction of 3-phenoxazinone, benzo[c]phenoxazin-3-one, and benzo[a]phenoxazin-9-one with piperidine and other similar amines leads to replacement of a hydrogen atom in the quinoid ring in the meta-position relative to the bridge nitrogen atom. Benzo[a]phenoxazin-9-one also forms 5,10-diamino derivatives. In all cases, the amine residue is displaced by thiophenol.
