A simple route for the synthesis of 1,4-benzoxazin-3-(4H)-ones is described herein. This method involves the reductive cyclization of 2-(2-nitrophenoxy)acetonitrile adducts in the presence of Fe/acetic acid in good to excellent yields. This system was compatible with various other functional groups.

Disclosed is a harmful arthropod control composition comprising, as an active ingredient, a fused heterocyclic compound represented by formula (1) [wherein A
1
and A
2
independently represent a nitrogen atom or the like; R
1
and R
4
independently represent a halogen atom or the like; R
2
and R
3
independently represent a halogen atom or the like; R
5
and R
6
independently represent a linear C1-C6 hydrocarbon group which may be substituted, or the like (provided that both R
