3-(2-Chloro­phen­yl)-N-(2-cyano-4-meth­yl-2-pent­yl)-5-methyl­isoxazole-4-carboxamide

The title compound, C₁₈H₂₀ClN₃O₂, is a potent new herbicide. X-ray analysis reveals that the benzene ring is twisted away from the isoxazole ring by 67.7 (1)°. The crystal packing is stabilized by inter­molecular N—H...N and C—H...O hydrogen bonds.
