Reaction Steps

Ethanolamine (2.44 g, 40 mmol) was added dropwise to a solution of diglycolic anhydride (2.32 g, 20 mmol) in pyridine (10 ml). The mixture was stirred for 5 minutes at ambient temperature and then heated at reflux for 2 hours. The volatiles were removed by evaporation and the residue was heated at 180° C. for 2 hours The reaction mixture was allowed to cool and was purified by column chromatography eluting with methylene chloride/methanol (9/1) to give 4-(2-hydroxyethyl)-3,5-dioxomorpholine (400 mg, 12.5%).
