2-{(E)-4-[4-(Trifluoromethyl)phenoxy]but-2-enyloxy}phenyl N-methylcarbamate

In the title compound, C19H18F3NO4, which was designed and synthesized as a dual-site inhibitor of insect AChE (acetylcholinesterase), the dihedral angle between the methylcarbamate group and the benzene ring is 72.47 (6)°. In the crystal, inversion dimers are linked by pairs of N—H...O hydrogen bonds.
