    Abstract: Novel 2-piperazinopyrimidine derivatives represented by following general formula (I), wherein R1 represents H or aralkyl; Y represents one of the following groups (II) to (VII), (wherein a and b represent positions to be bound to positions 4 and 5 of the pyrimidine ring, respectively, l1 and l2 each represents an integer of 2 to 4, l3 represents 2 or 0 and l4 represents 0 or 1, provided that l4 is 0 when l3 is 2, and l4 is 1 when l3 is 0, l5 represents 2 or 3, l6 represents 1 or 2, l7 represents 2 or 3, R2 represents OH or toluenesulfonyloxy, and R3, R4, R5, R6, and R7 each represents H or a lower alkyl). These compounds are useful as, for example, effective ingredients of herbicides.
