Procedure

(3,5-Dimethylisoxazol-4-yl)-1-(4-methoxyphenyl)-3-propyl-1H-pyrazole-4-carbonitrile (12 mg, 0.036 mmol) was dissolved in CH2Cl2 (3 ml) and BBr3 (1 M solution in DCM, 0.3 mL, 0.28 mmol) was added. The mixture was stirred at room temperature over night. Water and DCM were added and the phases were separated. The organic phase was purified on a silica plug to give 5-(3,5-dimethylisoxazol-4-yl)-1-(4-hydroxyphenyl)-3-propyl-1H-pyrazole-4-carbonitrile (5.4 mg, 47%).
