Reaction Conditions:

in N,N-dimethyl-formamide at 170; for 0.5 h;

Steps:

4 Embodiment 4: a kind of preparation method of 4-vinylphenol compound:

0.2 mmol of 3,5-dimethoxy-4-hydroxycinnamic acid and 1 mL of solvent DMF were added to the pressure-resistant reaction flask, and the reaction was heated and stirred in an oil bath at 170°C for 30 min; after the reaction, the reaction solution was extracted with ethyl acetate 3 times, followed by The organic layer was washed with water and saturated sodium chloride solution, and the washed organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography (V petroleum ether/V ethyl acetate=5 : 1) separation and purification to obtain 4-vinylphenol compound I-4 with a yield of 94%.
