Reaktionsschritte

Methyl 4-(4-(4-cyclopropyl-1H-imidazol-1-yl)picolinamido)thiophene-2-carboxylate (380 mg, 1.0 mmol) was dissolved in ethanol, hydrazine hydrate (0.26 mL, 5.2 mmol) was added, and the reaction was refluxed overnight. The solvent was removed under reduced pressure, and the solids were suspended in acetonitrile and filtered to afford 380 mg of 4-(4-cyclopropyl-1H-imidazol-1-yl)-N-(5-(hydrazinecarbonyl)thiophen-3-yl)picolinamide as a white solid. M+1=369.1
