Reaction Steps

A mixture of N-(2-hydroxyethyl)ethylenediamine (31.2 g), urea (23.4 g) and water (3 ml) was heated at 130° C. for 3 hours and at 210° C. for 8 hours and then distilled directly from the reaction mixture to give 1-(2-hydroxyethyl)-2-imidazolidinone (30 g) as an oil [(b.p. 150°-160° C. (0.2 mm)] which solidified to give a solid (m.p. 50-51).
