Reaction Steps

A solution of 2.0 g of (6-methyl-1,3-benzodioxol-5-yl)-carboxaldehyde in 15 ml of anhydrous tetrahydrofuran was dropwise added at a room temperature to a Grignard reagent prepared from 0.32 g of magnesium ribbon, 20 ml of anhydrous tetrahydrofuran and 1.4 g of bromoethane, followed by stirring for 2 hours. A saturated aqueous solution of ammonium chloride was added to the reaction mixture and the obtained mixture was distilled to remove the solvent. The residue was extracted with ethyl acetate and the organic layer was dried over magnesium sulfate and concentrated in a vacuum. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=2:8) to obtain 2.27 g of the title compound as a colorless crystal.
