4-amino-6-alkynyloxypyrimidine compounds shown by the formula (V)
which has a controlling activity against pests can be produced by the method which comprises
the first step which produces a 4-fluoro-6-alkynyloxypyrimidine compound shown by the formula (I)
by making a 4,6-difluoropyrimidine compound shown by the formula (II) react with an alcohol compound shown by the formula (III)
H—OR2 (III)
in the presence of a tertiary amine;
and the second step which produces the 4-amino-6-alkynyloxypyrimidine compound shown by the formula (V) by making the 4-fluoro-6-alkynyloxypyrimidine compound shown by the formula (I) react with an amine compound shown by the formula (IV)
公式(V)所示的4-氨基-6-炔基氧基嘧啶化合物具有对害虫的控制活性,可以通过以下方法制备:第一步,在三级胺的存在下,使公式(II)所示的4,6-二氟嘧啶化合物与公式(III)所示的醇化合物反应,从而产生公式(I)所示的4-氟-6-炔基氧基嘧啶化合物;第二步,在公式(IV)所示的胺化合物的存在下,使公式(I)所示的4-氟-6-炔基氧基嘧啶化合物与其反应,从而产生公式(V)所示的4-氨基-6-炔基氧基嘧啶化合物。
