Novel 4-(3-butynyl)aminopyrimidine derivatives represented by general formula [I] are useful as pest control agents. In general formula [I], R1 is a mono- or bi-cyclic ring which may contain 0 to 3 heteroatoms, for example, phenyl or oxazolyl; R2 is a hydrogen atom, —R, —OR, —C(O)OR, —C(O)NHR, —CONR2 (wherein R is straight-chain or branched C1-8 alkyl, or the like), hydroxyalkyl, or the like; R3 is a hydrogen atom, a halogen atom, acyloxy represented by (straight-chain or branched C1-8 aliphatic hydrocarbon group) —CO—O—, or the like; and R4 is a hydrogen atom, a halogen atom, C1-6 alkyl, or the like, or alternatively, R4 and R3 together with the carbon atoms on the pyrimidine ring may form a thiophene ring, a pyrrole ring, an imidazole ring, a benzene ring, a pyrimidine ring, a furan ring, a pyrazine ring, or a pyrrolidine ring.
通式[I]所代表的新型4-(3-丁炔基)氨基嘧啶衍生物可用作杀虫剂。在通式[I]中,R1是一个单环或双环环,可能包含0至3个杂原子,例如苯基或噁唑基;R2是氢原子,-R,-OR,-C(O)OR,-C(O)NHR,-CONR2(其中R是直链或支链C1-8烷基等),羟基烷基或类似物;R3是氢原子,卤素原子,酰氧基,表示为(直链或支链C1-8脂肪烃基)-CO-O-等;R4是氢原子,卤素原子,C1-6烷基或类似物,或者,R4和R3与嘧啶环上的碳原子一起可以形成噻吩环,吡咯环,咪唑环,苯环,嘧啶环,呋喃环,吡嗪环或吡咯烷环。
