    Abstract: Novel pyrimidinedione compounds and pharmaceutically acceptable salts thereof are disclosed. The synthesis of these compounds and their use as alpha 1a adrenergic receptor antagonists is also described. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia can be achieved.

    Abstract: Chloropyrimidine compounds, such as 4,6-dichloro-2-ethoxypyrimidine, were prepared in good yield and good purity from the corresponding hydroxypyrimidine compounds in the absence of organic solvents and with a reduced amount of phosphorus oxychloride by carrying out the reaction in the presence of a trialkylamine compound and phosphorus trichloride. The additions of hydroxypyrimidine compound and trialkylamine compound could be made in segments. The chloropyrimidine compounds produced were recovered in an improved manner by adding chlorine to convert the chlorophosphoric acid by-products and phosphorus trichloride to phosphorus oxychloride, diluting the mixture with additional chloropyrimidine compound and removing the phosphorus oxychloride by distillation, combining the residue with water and a base, distilling the trialkylamine compound from the resulting mixture, and removing the aqueous phase.

  • Patent number: 5914400
    Abstract: The present invention relates to a method of preparing BCH-189 and various analogs of BCH-189 from inexpensive precursors with the option of introducing functionality as needed. This synthetic route allows the stereoselective preparation of the biologically active isomer of these compounds, .beta.-BCH-189 and related compounds. Furthermore, the steochemistry at the nucleoside 4' position can be controlled to produce enantiomerically-enriched .beta.-BCH-189 and its analogs.
