  • Patent number: 6057350
    Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as alpha 1a adrenergic receptor antagonists. 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 are achieved.

C. in the presence of a water-immiscible or only partially water-miscible inert organic solvent,(b) in order to decompose the diazonium salt, the reaction mixture is treated simultaneously or subsequently with a diazonium salt decomposition catalyst,(c) the aqueous organic reaction mixture, or the organic phase obtained after removing the aqueous phase, is treated with an oxidizing agent at from 0.degree. to 100.degree. C. and(d) the organic phase is reacted with aqueous ammonia at from 0.degree. to 50.degree. C. and the saccharin is isolated from the aqueous phase in a conventional manner by acidifying with a strong acid.

  • Patent number: 4323469
    Abstract: The invention relates to a process for the preparation of carbamic acid phenyl esters of the formula (I) ##STR1## by acylating phenol derivatives of the formula (II) ##STR2## wherein R is alkyl having 1 to 8 carbon atoms, aryl, cycloalkyl having 5 or 6 carbon atoms, aralkyl having 7 to 16 carbon atoms which groups can be substituted by one or more alkyl groups,R.sup.1 is hydrogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms or acylamino,R.sup.2 is hydrogen, halogen, alkyl having 1 to 4 carbon atoms or alkoxy having 1 to 4 carbon atoms, or ifR.sup.1 and R.sup.2 represent alkyl and/or alkoxy, they can form together a carbocyclic ring.According to the invention the phenol derivatives of the general formula (II), wherein R.sup.1 and R.sup.2 are as defined above, are reacted with N-carbamoyl-saccharin derivatives of the formula (IV) ##STR3## wherein R has the same meaning as defined above, in the presence of a base.

  • Patent number: 4259499
    Abstract: A method of preparing 2-sulfochloride benzoates which comprises diazotizing any anthranilate to form a 2-diazonium chloride benzoate and thereafter reacting said 2-diazonium chloride benzoate with sulfur dioxide to form a 2-sulfochloride benzoate. The invention also provides for the total synthesis of saccharin which comprises pyrolyzing a 2-sulfochloride benzoate to form an o-sulfobenzoic anhydride and then ammonolyzing the o-sulfobenzoic anhydride to saccharin which is free of bitter tasting contaminants from such reactants.
