Reaction Steps
At 0° C., a mixture of 40 ml of ethyl acetate and 1 cm3 of ethanol is added drop by drop to a suspension of 3.5 g (0.15 mole) of sodium in balls in 200 ml of xylene. 22 g (0.1 mole) of 5-(1,1-ethylenedioxy-ethyl)-2-methoxy benzaldehyde dissolved in 50 ml of xylene are then added. The reaction medium is allowed to return to ambient temperature and is stirred for 3 hours. 50 ml of acetic acid are then added. After total disappearance of the sodium, 40 ml of water are added. After extraction with ether, washings with sodium hydroxide then with water up to neutrality, the ethereal phases are evaporated to obtain 24 g (oil) of the expected product.
