実験手順
A mixture of the above isothiourea salt (8.5 g, 27.0 mmol) and hydrazine (1.4 g, 27.0 mmol) in 80 ml of ethanol is heated to reflux for 4 hr. The mixture is cooled and the solvent removed. The residue is diluted with 80 ml of water and filtered. A 20 ml aliquot of the resulting aqueous filtrate (2.0 g, 11.9 mmol) is mixed with 2-acetylnicotinic acid (2.0 g, 11.9 mmol) in 6 ml of methanol and stirred at RT overnight. A bright yellow solid is collected by filtration and dried to give 2-[methyl(3-carboxy-2-pyridyl)methylene]-N-(3-fluorophenyl)hydrazinecarboximidamide, (compound 16).
