Reaction Steps
1 g of 2,3-dihydro-1,4-benzodioxin-6-yl acetate (5.149 mmol) is dissolved in a solution of methanol (7.5 ml) and, under an argon atmosphere, the mixture is made basic, dropwise, with a 10% sodium hydroxide solution. The mixture is stirred at ambient temperature for 4 hours. At the end of the reaction, the methanol is evaporated and the reaction medium is acidified (to pH=1) with a 2N HCl solution and then washed with ethyl acetate. After extraction, drying over MgSO4 is carried out and the product is concentrated in vacuo. Purification on a silica column allows an oil to be obtained (eluant:PE/AcOEt 8/2 then 7/3).
