PURPOSE: A process for preparing a methoxy acrylate derivative containing sulfur having a new structure by bonding a 4-quinolinone group or a benzothiopyrane-4-one group to a methoxy acrylate group through sulfur is provided. Whereby, the product has an excellent antibacterial activity against various plant pathogenic bacteria and is useful as a microbial agent. CONSTITUTION: The titled compound of formula(1) is prepared by the reaction of a compound of formula(2) with a compound of formula(3) at -20 to 50deg.C in the presence of an inorganic or organic base. In formulae, R1, R2, R3 and R4 are each independently H, halogen, C1-3 alkyl, C1-3 alkoxy, nitro or C1-3 haloalkyl, R5 is H, halogen, C1-3 alkyl or -C(=O)-R6, R6 is C1-6 alkyl, X is S or NH, Y is CH or N, Z is halogen, toluene sulfonate(OTs) or methane sulfonate(-OMs).
