Procedure
A mixture of (4-Chloromethyl-phenyl)-methanol (600 mg, 3.8 mmol), ethyl 1H-pyrazole-4-carboxylate (537 mg, 3.8 mmol) and potassium carbonate (2.6 g, 19 mmol) in 30 mL acetone was stirred at 50° C. for 3 h. The mixture was filtrated and concentrated in vacuo. The crude was purified by preparative HPLC (Waters Sunfire Prep C18 PBD 5 um, 30×100 mm, 5 to 100% ACN and 0.1% TFA, flow 40 ml/min) to yield the title compound. LCMS (method A) RtA=1.403 min; [M+H]+=261.0.
