FIELD: organic chemistry. SUBSTANCE: product: derivatives of pyrimidine of the general formula (I) 
where R lower imidazole or alkylthio-group, or group of the formula OR3 where R3 hydrogen, alkyl possibly substituted with cyano-, alkoxy-, alkylthio-, phenyl, phenylthio-, phenylsulfinyl, phenylsulfonyl, benzylhydroxy-, alkylcarbonyloxy-, alkoxycarbonyloxy- or phthalimidoyl-group; or R3 alkenyl, alkynyl, alkylydeneamino-group, alkaline metal or group -CH2-C(O)-R4 where R4 phenyl or alkyl; R1 hydrogen or alkyl; R2 hydroxy, alkoxy-group possibly substituted with halogen, phenoxy-, benzyloxy-, alkylhydroxycarbonyl, cycloalkyl-C3-C6 or alkoxy-group, or R2 alkenyl possibly mono- or disubstituted with halogen or phenyl, alkynylhydroxy-group, phenyl possibly substituted with halogen, alkyl or alkoxy-group, phenoxy-group, benzylhydroxy-group possibly substituted with halogen, alkoxy-group, phenylamino-group or group -OC(O)R5 where R
where R hydroxy-, alkoxy or benzylhydroxy-group; R1 hydrogen, lower alkyl; A and B alkoxy-group; Y oxygen or sulfur and also phenyl-derivatives of the formula (III) 
where Y oxygen; R - hydroxy- or alkoxy-group; R1 alkyl. Alkyl in indicated substituents is lower one; R2 phenyloxy- or benzyloxy-group, and these compounds are intermediate products for synthesis of compounds of the formula (I). Method of struggle against weed is carried out by treatment of plants or areas where plants were grown with compound of the formula (I) taken at concentration 0.016-1 kg/ha. Herbicide composition has active components compounds of the formula (I) at concentration 2-30 wt. -% and the special additions the rest. Synthesized compounds were used in agriculture. EFFECT: improved method of synthesis. 6 cl, 14 tbl
