Reaction Steps

To a 500 mL RB flask fitted with magnetic stirrer was charged with water (160 mL). To the stirred solvent was added 4-hydroxybenzaldehyde (25.0 g, 122.12 mmol) and 2,2-dimethyl-1,3-dioxane-4,6-dione (25.0 g), it was heated at 75° C. for 2 h. The RM was cooled to obtain the solid, filtered and was washed with water, then dried to obtain the product (34.0, yield: 83.74%).
