Ethylene carbonate → 2-(4-Iodo-1H-pyrazol-1-yl)ethanol

Participants

Reaction Steps

A solution of 4-iodopyrazole (14.3 g, 73.9 mmol) and ethylene carbonate (6.83g, 77.6 mmol) in DMF (50 mL) was stirred at 125° C. for 24 h. The cooled solution was concentrated under vacuum to leave a brown oil. The residue was purified by FCC using 30-70% EtOAc in DCM to give the title compound (9.36 g, 53%). LCMS (Method 3): Rt 2.24 min, m/z 239 [MH+].
