Abstract

New compounds usable as anti- allergics, having the structure wherein R<1> is hydrogen or lower alkyl; R<2> is carboxyl, hydroxymethyl, lower alkanoyloxymethyl or lower alkoxycarbonyl; R<3> is hydrogen, lower alkyl or benzyl; R<4> and R<5> are the same or different and are selected from hydrogen, alkyl of 1 to 4 carbons, alkoxy of 1 to 4 carbons, hydroxy, lower alkanoyloxy of 1 to 4 carbons, nitro, halogen, trifluoromethyl, benzyloxy, or benzyloxy having a lower alkoxy, halogen, hydroxy, nitro, or trifluoromethyl substituent; and physiologically prepared by cyclisation to form the prepared by cyclisation to form the pyrimidine ring, optionally followed by modification of the groups at R<2>.
