실험 절차

(3E)-4-(dimethylamino)but-3-en-2-one (255 mg, 2.25 mmol) and 2-hydrazinopyridine (369 mg, 3.38 mmol) were added to ethanol (3 ml). The reaction mixture was heated to 150° C. in the Biotage Initiator Series microwave reactor. After 30 minutes, the reaction mixture was cooled and concentrated. The residue was purified by column chromatography on silica gel, (ethyl acetate/isohexane gradient) to afford 2-(3-methyl-1H-pyrazol-1-yl)pyridine (faster eluting isomer) and 2-(5-methyl-1H-pyrazol-1-yl)pyridine (slower eluting isomer).
