In the next step the carbonyl function of the 1H-quinazolin-4-one derivative, or the 1H-pyrimidin-4-one derivative with a condensed 5-membered heterocyclic ring structure is reacted further e.g. with phosphorous pentasulfide or Lawesson's reagent to yield the 1H-quinazolin-4-thion derivatives, or the 1H-pyrimidin-4-thion one derivatives with a condensed 5-membered heterocyclic ring structure.
