Dimethylformamide → HCID 23157233, compound

Participants

Reaction Steps

A mixture of methyl 4-[(3-tert-butyl-5-hydroxy-1H-pyrazol-1-yl)methyl]benzoate (2.00 g, 6.94 mmol), benzyl bromide (0.91 mL, 7.7 mmol), potassium carbonate (0.96 g, 6.9 mmol) and N,N-dimethylformamide (25 mL) was stirred overnight at room temperature. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (30% ethyl acetate/hexane) to give the title compound (2.14 g, yield 81%) as a yellow oil.
