While cooling with the ice bath 120 mg sodium hydride (60% in mineral oil) are added. The reaction mixture is then stirred for 30 minutes at ambient temperature. While cooling with the ice bath 0.289 ml 1-iodopropane are added. The reaction mixture is then stirred overnight at ambient temperature, then combined with a saturated NaCl solution. The product is extracted with ethyl acetate. 0.569 g product are obtained as an oil.
