The reaction mixture was stirred for a further 2 h. A solution of ammonium chloride (2 ml) was added followed by methylene chloride (250 ml) and decalite. The mixture was filtered and the filter was washed with additional methylene chloride (500 ml) and ethanol (100 ml). The combined organic phases were evaporated to give crude 3,3-bis-(2-furanyl)-prop-2-en-1-ol in 953 mg (88%) yield.
