As part of structural studies of 6-ethoxy-2,3,4-tetrahydro-2,2,4-trimethylquinoline derivatives, the crystal structure of the title compound, C 14 H 21 NO, has been investigated. The conformation of the tetrahydropyridine ring differs markedly from that of similar compounds.
All bond lengths and anlges in the title compound, C 15 H 9 F 5 N 2 O 2 , an inhibitor of chitin synthesis, are normal. The urea linkage adopts an essentially planar con®guration, with an intramolecular NÐHÁ Á ÁO hydrogen bond. Intermolecular NÐHÁ Á ÁO hydrogen bonds link two adjacent molecules into
Each of the three independent molecules of the title compound, C~16~H~20~N~2~, has near-perpendicular benzene rings and pyramidal N atoms. Hydrogen bonding in the structure is rather inefficient.
