- WO 04/0162581 disclose processes to prepare 4-[[4-[[4-(2-cyanoethenyl)-2,6- dimethylphenyl]amino]-2-pyrimidinyl]amino]benzonitrile.
- a good drug candidate should preferably also be stable chemically as well as physically; should have an acceptable toxicity profile; should have an acceptable bioavailability.
- the bioavailability of the compound influences the dose of the compound required for 30 administration in order to reach a therapeutically effective concentration of the compound in the patient.
- Compounds having a low bioavailability need to be administered in higher doses compared to compounds having a higher bioavailability.
- Possible consequences of the need for higher doses may comprise : an increased risk to adverse effects; an increase in the size of the dosage form; an increase in the frequency 35 of administration. These factors may influence adherence to antiretroviral therapy. Therapy adherence is one of the most important factors influencing the effectiveness of HIV treatment. Increase in dosing frequency and increase in pill size may lead to reduced therapy adherence and hence reduced therapy effectiveness.
- bioavailability of a compound intended to be administered orally is dependent on the compounds solubility in water as well as the compounds permeability (its ability to be absorbed across the intestinal membrane).
- BCS Biopharmaceutics Classification System
- Class 2 Low Solubility - High Permeability
- Class 3 High Solubility - Low Permeability
- Class 4 Low Solubility - Low Permeability
- Compounds with a low solubility or a low permeability may suffer from a low bioavailability when administered orally.

- 4-[[4-[[4-(2-cyanoethenyl)-2,6-dimethylphenyl]amino]-2- pyrimidinyl]amino]benzonitrile does not only exhibit a low solubility in water, but also in an acidic environment. Consequently, when administered orally in a conventional solid dosage form, a low bioavailability may be expected.
- the prepared salts still belong to BCS class 2. Thus, also for the prepared salts a low bioavailability could be expected.
