An efficient method for producing a halogenated cyclic compound, in particular a halogenated nitrogen-containing heterocycle, which enables high yields and product purity and uses readily available starting materials as starting materials Offer. A method for producing a cyclic compound of the following formula: (a) adding an acid halide of formula (I) to a vinyl ether of formula (II) to form an addition product; (B) reacting the addition product with a compound of formula (III). [R 1 is a halogenated alkyl group; Z and Y are each independently a carbon or heteroatom; A is 0, 1, 2, or 3 atoms in the ring; a linking group between Z and Y], R 1 -C (O) -X [X is halogen; R 1 is the same as above], Y-A-Z (III) [Z, Y and A are the same as above] [Selection figure] None |
