Participants

Reaction Conditions

Reaction Steps

Add sodium carbonate (5.80 g, 41.7 mmol) to a solution of 4-bromopyrazole (3.10 g, 20.9 mmol) and methyl 3-bromomethylbenzoate (4.8 g, 20.9 mmol) in 40 mL of dimethylacetamide. Stir the mixture at 60° C. overnight. Cool the reaction to room temperature and pour into 300 mL of ice water. Collect the resulting solid by filtration and dry to afford 6.0 g, 98% yield of 3-(4-bromo-pyrazol-1-ylmethyl)-benzoic acid methyl ester.
