Procedure
The starting material required is prepared as follows: A mixture of 17.2 g of ethyleneurea and 19.5 g of p-fluorobenzene sulphonyl chloride is heated at 110° for 3 1/2 hrs. The residue is recrystallized from a mixture of methanol and water to afford 1-(4-fluorophenylsulphonyl)-2-oxo-tetrahydroimidazole which melts at 183°-185°.
