- Abstract
Heterocyclization of 3-[(alkylsulfanyl)methyl]pentane-2,4-diones with isonicotinic acid hydrazide in ethanol in the presence of a catalytic amount of aqueous HCl under microwave irradiation or without it afforded new 4-{4-[(alkylsulfanyl)methyl]-3,5-dimethyl-1H-pyrazole-1-carbonyl)pyridines. 3-[(Alkanesul-fonyl)-methyl]pentane-2,4-diones under similar conditions were converted to the corresponding 4-[(alkanesul-fonyl)-methyl]-3,5-dimethyl-1H-pyrazoles.
