Reaction Conditions

Reaction Steps

To 3-hydroxybenzaldehyde (available from Aldrich) (24.4 g, 200 mmol) in water (1000 mL) at 85° C., was added 2,2-dimethyl-1,3-dioxane-4,6-dione (available from Aldrich) (28.8 g, 200 mmol). The resulting mixture was then stirred at 85° C. for 2 hours. The reaction was allowed to cool and then filtered to provide 8.1 (41.3508 g, 83.3% yield) as a yellow solid.
