  • Patent number: 6683086
    Abstract: The subject invention concerns novel compounds that are useful as ultrashort acting hypnotic barbiturates. Specifically exemplified are derivatives of barbituric and thiobarbituric acids. They are rapidly metabolized by blood and tissue enzymes to form polar metabolites with no hypnotic activity and which are rapidly eliminated.

  • Patent number: 6673925
    Abstract: Method of producing thiobarbituric acid derivatives of formula I wherein R1 is SH, S−M+ or CH3S—, and M+ is an alkali metal ion, by hydrogenolysis of a compound of formula II wherein R2 is chlorine or CH3O—, with a) a hydrogenolysis agent in the presence of an inert solvent and by a direct reaction of the hydrogenolysis product with an alkali metal methylate in methanol, or b) with a hydrogenolysis agent in the presence of an inert solvent and in the presence of a methylation reagent, and subsequently with an alkali metal methylate in methanol, as well as the use of these compound of formula I in the production of 7-[(4,6-dimethoxy-pyrimidin-2-yl)thio]-3-methylphthalide.

  • Patent number: RE38934
    Abstract: A method of N-alkoxyalkylating ureides according to the invention comprises reacting a ureide of structure I with an alkylating agent of structure III in the presence of a basic catalyst in an aprotic reaction medium. The ureide may be a 5,5-disubstituted barbituric acid, or it may be phenytoin, glutethimide, and ethosuximide. The alkylating agent is an ester of a sulfonic acid. The base may be a hydride or amine. A preferred process comprises N-alkoxyalkylating 5,5-diphenyl-barbituric acid with methoxymethyl methanesulfonate in the presence of di-isopropyl ethyl amine and isolating the resultant N,N?-bismethoxymethyl-5,5-diphenyl-barbituric acid. The invention also contemplates the novel compounds N-methoxymethyl-5,5-diphenylbarbituric acid, N-methoxymethyl ethosuximide, and N-methoxymethyl glutethimide, and a method comprising administering them to a patient.
