반응 단계
A heterogeneous mixture containing 1.42 mol of 3-methoxycatechol, 1.57 mol of 1,2-dibromoethane, 1.42 mol of potassium carbonate and 4 g of copper powder in 150 ml of glycerol is heated at 110° C. for 15 hours. After cooling, the mixture is poured into 1 l of water. The aqueous phase is extracted with ethyl ether. The ether phases are then washed with 1N sodium hydroxide, dried and evaporated, and give the expected product.
