Reaction Steps

3-ethyl-1-(4-methoxyphenyl)-5-(3-methylfuran-2-yl)-1H-pyrazole-4-carbonitrile (5 mg, 0.02 mmol) was dissolved in CH2Cl2 (3 mL) and BBr3 (1 M solution on DCM, 0.3 mL, 0.3 mmol) was added and stirred at room temperature over night. The reaction was quenched using water and extracted with CH2Cl2. Concentration gave a crude 3-ethyl-1-(4-hydroxyphenyl)-5-(3-methylfuran-2-yl)-1H-pyrazole-4-carbonitrile (5 mg, 0.02 mmol, 100%) which was used as such in the next step.
