Synthesis of N, N΄3, 4-Dialkylamino-1, 2, 5-Oxadiazoles
N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚C. Under similar conditions N, N΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and N, N΄-3, 4-di(isopropylamino)...
متن کامل3-(2-Chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethyl-N-[3-(trifluoromethyl)phenyl]cyclopropanecarboxamide
In the title mol-ecule, C(16)H(14)ClF(6)NO, the cyclo-propane ring forms a dihedral angle of 70.82 (18)° with the benzene ring. The torsion angles about the ethyl-ene and amide bonds are -2.2 (5) (Cl-C-C-C) and 0.8 (5)° (O-C-N-C). A supra-molecular chain propagated by glide symmetry along [001] and mediated by N-H⋯O hydrogen bonds is observed in the crystal packing.
متن کاملN,N-Dimethyl-3-(1-naphthyloxy)-3-(2-thienyl)propan-1-amine
The title compound, C(19)H(21)NOS, is an inter-mediate for the synthesis of duloxetine hydro-chloride. In the mol-ecular structure, the thio-phene and naphthalene ring systems make a dihedral angle of 87.5°. All bond lengths and angles involving heteroatoms are as expected. In the crystal structure, no classical hydrogen bonds are found.
