Pyridine → 1-(3-methyl-1H-indazol-1-yl)Ethanone

Participants

Reaction Steps

3-Methylindazole (1.00 g, 7.6 mmol) was dissolved in 10 ml THF and stirred at RT under a blanket of argon. Pyridine (0.64 ml, 7.9 mmol) was added followed by Ac2O (0.79 ml, 8.3 mmol) and catalytic DMAP (90 mg, 0.7 mmol). The reaction proceeded for 2 h and was then partitioned between 1N HCl and dichloromethane. The organic phase was dried over MgSO4 and concentrated in vacuo to a tan solid (1.2 g, 91% yield).
