Participants

Reaction Steps

2,2-Dimethyl-1,3-dioxane-4,6-dione (1.72 g) was suspended in anhydrous pyridine (20 ml) and cooled to 0° C. (2-methoxyethoxy)acetyl chloride (2 g) was added slowly. The mixture was stirred at room temperature for 3 h. The mixture was poured into 2 N HCl (30 ml) and extracted with DCM (×3). The combined organic phase was washed with water, brine, dried over sodium sulfate and concentrated in vacuo. The orange oil was dissolved in EtOH (20 ml) and was refluxed for 7 h. The solvent was removed in vacuo and the brown oil was Kugelrohr distilled affording the title compound as a colourless oil (1.55 g).
