Abstract

Improvements introduced in the object of the main patent No. 425,238 applied for on April 10, 1974 for: "A process for the preparation of a pyrimidin-4- (3H) -one", specifically molten pyrimidines where it is prepared by a method known to be for analogous compounds, a compound of the formulas: **(See formula)** and the pharmaceutically acceptable cationic salts thereof, wherein R is selected from the group consisting of methyl, ethyl, acetyl and COR ° where R ° is selected from the group consisting of hydroxy, alkoxy, hydroxyalkoxy, amino and hydroxyamino; Y is selected from the group consisting of (a) hydrogen and (h) alkyl, carbalkoxyalkyl, carboxyalkyl, - (CH2) m-O-CO-C5H6 and - (CH2) m-O-alconoyl; with the proviso that curd R is methyl or ethyl, Y is selected from group (b); and when R is COR ° where R ° is amino or hydroxyamino, Y is hydrogen; it is an integer from 2 to 4; R1 is selected from the group consisting of hydrogen, alkyl, and phenyl; R2, R3, R4 and R5 are each selected from the groups consisting of (a) hydrogen, alkyl, alkoxy, halo, benoyloxy, methylthio and methylsulfinyl; and (b) hydroxy, thiol, alkanoyloxy, benzylthio, benzoyloxy, and benzylsulfonyl.
