Procedure

A suspension of 6-(1-methyl-1H-pyrazol-4-yl)pyridine-3-carboxylic Acid (0.48 g) in thionyl chloride (5.0 ml) was stirred at room temperature for 2 hours. The volatile material was removed under reduced pressure to afford 6-(1-methyl-1H-pyrazol-4-yl)pyridine-3-carbonyl chloride as a solid, which was utilized without further purification.
