Beschreibung
Zusammenfassung:	Geminal dihalogen derivatives of condensed pyrimidine-4-one compounds of the general formula [wherein R represents hydrogen, lower alkyl, or lower alkoxycarbonyl; R represents hydrogen, lower alkyl, ester group, carboxy or a derivative thereof, cyano, phenyl or halogen; R represents hydrogen, lower alkyl or phenyl; X represents halogen; n is the integer 0, 1 or 2] and the salts and optically active antipodes thereof are of interest as chemical intermediates; some also exhibit a variety of physiological activities and may be formulated into pharmaceutical compositions in conventional manner. The novel compounds can be made by halogenating a corresponding starting material wherein one or both X-substituents are hydrogen.
