A method for producing an N-methyl-methoxyiminoacetamide derivative represented by the following general formula (I)
(wherein R3 represents a hydrogen atom or a group represented by a general formula -C(R4)(R5)-Ar (wherein R4 and R5 independently represent a hydrogen atom or a C1-C4 alkyl group and Ar is an optionally substituted aryl group or an optionally substituted heteroaryl group)), which comprises allowing an acetal derivative represented by the following general formula (III)
(wherein R1 and R2 independently represent a C1-C4 alkyl group, or R1 and R2 in combination represent a C2-C4 alkylene group) to react with an oxyamine derivative represented by the following general formula (II)
H2NO-R3 (II).
The compound of general formula (I) is an excellent agricultural horticultural fungicide described in an unexamined published Japanese patent application (kokai) No. 7-076564.
