Methyl 3-amino-4-butanamido-5-methylbenzoate
The title compound, C(13)H(18)N(2)O(3), is an inter-mediate in the synthesis of compounds with medicinial applications. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds.
متن کامل3-Amino-5-methyl-5-(4-pyridyl)hydantoin
The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...
متن کامل5 - Amino - 3 - methyl - 1 , 2 , 4 - thiadiazole
An improved procedure for isolation of 5-amino-3-methyl-1,2,4-thiadiazole in pure form on a multi-gram scale without chromatography is reported. Its 1H and 13C-NMR and IR data are presented and previously published erroneous data corrected. The molecular structure is confirmed by X-ray diffraction which shows layers consisting of an elaborate two-dimensional hydrogen bonded network of molecules.
متن کامل5-Amino-3-methyl-1,2-oxazole-4-carbonitrile
In the title compound, C(5)H(5)N(3)O, the isoxazole ring is essentially planar, with a maximum deviation of 0.007 (1) Å from the least-squares plane. The N atom of the amine group exhibits sp(2) character (sum of bond angles around this atom = 358°). In the crystal, mol-ecules are aggregated by two kinds of N-H⋯N hydrogen bonds into fused R(2) (2)(12) and R(6) (6)(26) rings, forming a slightly ...
متن کاملMethyl 2-amino-4-(3-chloropropoxy)-5-methoxybenzoate
The asymmetric unit of the title compound, C(12)H(16)ClNO(4), contains two crystallographically independent mol-ecules. The benzene rings of the two independent mol-ecules are oriented at a dihedral angle of 88.50 (3)°. Intra-molecular N-H⋯O hydrogen bonds involving the methoxybenzoate carbonyl group in each molecule result in the formation of two planar, six-membered rings, oriented at dihedra...
