4-(2H-1,3-Benzodioxol-5-yl)-1-(4-methylphenyl)-1H-pyrazol-5-amine
In the title compound, C17H15N3O2, two independent mol-ecules (A and B) comprise the asymmetric unit. The major conformational difference arises in the relative orientation of the pyrazole ring amine and dioxole substituents which are anti in A and syn in B. The five-membered dioxole ring in each mol-ecule has an envelope conformation with the methyl-ene C atom as the flap. The mean plane throu...
متن کاملA monoclinic polymorph of 4-(2H-1,3-benzodioxol-5-yl)-1-(4-methylphenyl)-1H-pyrazol-5-amine
The title compound, C17H15N3O2, is a monoclinic polymorph (P21/c with Z' = 1) of the previously reported triclinic (P-1 with Z' = 2) form [Gajera et al. (2013 ▸). Acta Cryst. E69, o736-o737]. The mol-ecule in the monoclinic polymorph features a central pyrazolyl ring with an N-bound p-tolyl group and a C-bound 1,3-benzodioxolyl fused-ring system on either side of the C atom bearing the amino gr...
متن کامل2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one
The title compound, C(20)H(16)Cl(2)N(4)O, has two mol-ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol-ecule and 56.8 (3)° in the other independent mol-ecule. The amino group of the dihydro-pyrazolone unit of one mol-ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro-pyrazolone system of the other mol-ecule. The resul...
متن کامل4-(4-Fluorophenyl)-1-(4-nitrophenyl)-3-(pyridin-4-yl)-1H-pyrazol-5-amine
In the crystal structure of the title compound, C(20)H(14)FN(5)O(2), the pyrazole ring forms dihedral angles of 59.3 (2), 25.6 (2) and 46.0 (2)° with the directly attached 4-fluoro-phenyl, pyridine and nitro-phenyl rings, respectively. The crystal packing is characterized by inter-molecular N-H⋯N and N-H⋯O hydrogen bonds.
متن کامل(R)-4-[2-(Methylsulfanyl)pyrimidin-4-yl]-1-(tetrahydrofuran-3-yl)-1H-pyrazol-5-amine
The title compound, C(12)H(15)N(5)OS, was obtained by reaction of 2-(2-(methyl-thio)pyrimidin-4-yl)-3-oxopropane-nitrile with (tetra-hydro-furan-3-yl)hydrazine dihydro-chloride, and the racemic product was subsequently separated by chiral chromatography (first peak; [α](D) (20) = +51.3°). The chiral center at the substituted atom of the tetra-hydro-furanyl group has an R-configuration. The pyri...
