Reaction Steps
To a solution of 3,3-bis-(3-methyl-thiophen-2-yl)-acrylic acid ethyl ester (2.12 g, 7.27 mmol) in THF (20 ml) was added a solution of DIBAL-H (1.5 M in toluene, 33 ml, 49.5 mmol) at −20° C. The reaction mixture was stirred for a further 2 h. A solution of ammonium chloride was added followed by methylene chloride (150 ml) and decalite. The mixture was filtered and the filter was washed with additional methylene chloride (500 ml). The combined organic phases were evaporated to give crude product. Purification on column chromatography gave 3,3-bis-(3-methyl-thiophen-2-yl)-prop-2-en-1-ol in 376 mg (21%) yield.
