Disclosed herein is an antihypertensive preparation containing, as an active component, a novel quinazoline derivative represented by the following general formula or a salt thereof: ##STR1## wherein R.sup.100 means a hydrogen atom or methoxy group, R.sup.200 and R.sup.300 denote individually a hydrogen atom or lower alkoxy group, R.sup.400 is a hydrogen atom or amino group, l stands for 2 or 3, and Het is a specific hetero ring group.
The present invention relates to novel 2-piperazinopyrimidine derivatives represented by the following general formula [I] which are useful as, for example, an active ingredient of herbicides ##STR1## wherein R.sup.1 is a hydrogen atom or an aralkyl group and Y is one of the groups represented by the following general formulas [II] to [VII] ##STR2## (wherein a and b are positions to be bound to positions 4 and 5 of the pyrimidine ring of the formula [I], respectively; l.sub.1 and l.sub.2 each are an integer of 2 to 4; l.sub.3 is 2 or 0; l.sub.4 is 0 or 1, provided that l.sub.4 is 0 when l.sub.3 is 2 and l.sub.4 is 1 when l.sub.3 is 0; l.sub.5 is 2 or 3; l.sub.6 is 1 or 2; l.sub.7 is 2 or 3; R.sup.2 is a hydroxyl group or a toluenesulfonyloxy group; and R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each are a hydrogen atom or a lower alkyl group).
