Potassium Carbonate → 1-(4-Methoxybenzyl)-4-nitro-1H-pyrazole

Participants

Reaction Steps

A solution of 4-nitro-1H-pyrazole (500 mg, 4.42 mmol; Bionet Research, Cornwall, UK) in DMF (5 mL) was treated with potassium carbonate (400 μL, 6.63 mmol) and 4-methoxybenzyl chloride (600 μL, 4.42 mmol). The reaction was stirred at room temperature for 2 h, then diluted with DCM (200 mL) and washed with water (4×40 mL). The organic layer was then dried (MgSO4), filtered and concentrated in vacuo to give the crude product, which was used in the next step without further purification.
