- 1Sammendrag Summary A purification process is described which is capable of separating zaleplon and a regioisomer of zaleplon which tends to be formed as a by-product of the chemical synthesis of zaleplon, leading to substantially pure zaleplon. In addition, new crystalline forms of zaleplon are obtained in the process. Det er beskrevet en renseprosess som er i stand til å separere zaleplon og en regioisomer av zaleplon som har tendens til å dannes som et biprodukt ved den kjemiske syntese av zaleplon, og som fører til hovedsakelig rent zaleplon. Dessuten oppnås det nye krystallinske former av zaleplon i prosessen.
