Benzyl Bromide → 1-benzyl-1H-pyrazole-3-carbaldehyde

Participants

Reaction Steps

To a solution of benzyl bromide (0.29 g) in N,N-dimethylformamide (9 ml) was added 1H-pyrazole-3-carboxaldehyde (0.15 g) and potassium carbonate (0.24 g). The mixture was stirred at room temperature for 24 hours, silica gel was added, the solvent removed by evaporation and the crude material purified by chromatography (isohexane:ether, 2:1) to give the product as an oil (0.18 g).
