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.
