Chem., 22(6), 1611-14 (English) 1985. CODEN: JHTCAD. ISSN: 0022-152X. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) 2-Hydrazinopyridine reacts with RR1C:C:CHCN (R = H, R1 = Bu; R = Me, R1 = Me, Et, Pr; R = R1 = Et) to give 5-amino-3-alkyl-1-(2-pyridyl)pyrazoles I in excellent yields. I (R = R1 = Et) has anticonvulsant and anti-electroshock properties. PhCYCCN also reacts with hydrazinopyridine to give 5-amino-3-phenyl-1-(2-pyridyl)pyrazole quant. .

ISBN: 86-435-0722-9(Slovenian) 2005. CODEN: 69HTUD. DOCUMENT TYPE: Conference; (computer optical disk) CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Reactions of 2-acetylamino-3-(dimethylamino)propenoates with various hydrazines were studied. First step in the reactions was acid-catalyzed substitution of dimethylamino group with hydrazine carried out in aq. media. In this manner some novel alkyl 3-(2-arylhydrazono)-2-(acylamino)propenoates were prepd. in hydrazonic form only. In the second step cyclization of previously obtained alkyl 3-(2-arylhydrazono)-2-(acylamino)propenoates was carried out. Some reactions afforded desired pyrazoles when reaction mixt. was refluxed in neutral media (ethanol). Basic-catalyzed reactions (with triethylamine) showed better results. ..
