Reaction Steps

1.96 g N-hydroxyphthalimide and 765 mg of 3-chloromethylpyrazole hydrochloride were added to a mixture of 0.28 g of sodium and 20 ml of ethanol under cooling in ice-bath and the resulting mixture was stirred for 2.5 hours at room temperature. The solvent was distilled off and water was added to the residue. The mixture was extracted with chloroform and the extract was washed with SSB and SSC and then dried with sodium sulfate. The solvent was distilled off and the residue was washed with ether to give 3-(phthalimidooxymethyl)pyrazole with mp 166°-168° C.
