Methyl 4-amino-3-methylbenzoate
In the mol-ecule of the title compound, C(9)H(11)NO(2), the methyl C and amino N atoms bonded to the benzene ring lie in the ring plane. Intra-molecular C-H⋯O hydrogen bonding results in the formation of a five-membered planar ring, which is oriented at a dihedral angle of 2.73 (3)° with respect to the benzene ring, so they are nearly coplanar. In the crystal structure, inter-molecular N-H⋯O hy...
متن کاملMethyl 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 کاملTriphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
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.
