Participants

Reaction Steps

To a suspension of 4-(3-methylpyrazol-1-yl)benzoic acid (1.84 g) in dichloromethane (25 ml) was added oxalyl chloride (1.16 g) and one drop of dimethylformamide. The mixture was stirred at room temperature for 18 hours and the volatile material was removed under reduced pressure. Dichloromethane was added, the solution filtered, and the solvent evaporated under reduced pressure to yield 4-(3-methylpyrazol-1-yl)benzoyl chloride as a yellow oil (1.76 g), which was utilized without further purification.
