Reaction Steps
To a solution of Ethyl-4-pyrazole-carboxylate (14.0 g, 100 mmol) in Acetone (200 ml) was added potassium carbonate (27.6 g, 200 mmol) and Benzyl Bromide (12 ml, 100 mmol). The mixture was heated to 60° C. and stirred for 14 hours. The reaction mixture was cooled and filtered to remove any solids. The filtrate was concentrated and the residue was purified using column chromatography (3:1 Hexanes:Ethyl Acetate) to yield ethyl 1-benzylpyrazole-4-carboxylate (19.0 g, HNMR)
