The title compound, C 9 H 12 N 2 O 3 , was synthesized by the reaction in ethanol of ethane-1,2-diamine and 3-[bis(methylthio)methylene]-6-methyl-3,4,5,6-tetrahydro-2H-pyran-2,4dione. Two intramolecular N-HÁ Á ÁO hydrogen bonds induce a high degree of planarity.
The title compound, C 24 H 17 N 4 Cl, was synthesized by the reaction of 5-amino-3-methyl-1-phenylpyrazole with 3-(2chlorophenyl)-1-(2-pyridyl)prop-2-en-1-one in glycol under microwave irradition. X-ray crystal structure analysis reveals that the substituted pyridine ring is almost coplanar with the
