To provide a substituted amino vinyl ether derivative.

The substituted amino vinyl ether derivative is represented by formula (1), wherein m is an integer of 1; n is an integer of 2; R1, R2 and R3 are each independently a hydrogen atom, an alkyl group or an aryl group, and a ring may be formed by binding R1 and R2, or R2 and R3; R8 and R9 are each independently a hydrogen atom, an alkyloxycarbonyl group, an aryloxycarbonyl group, an acyl group, a benzoyl group, an alkylsulfonyl group or an arylsulfonyl group; with the proviso that at least one of R8 and R9 is a substituent except a hydrogen atom, and R8 and R9 may be bonded to each other to form a dicarbonyl group or a disulfonyl group having a structure formed into a ring.
