There were 3 bands that could be isolated from this column, first 2 brown bands and then one green band. The second brown band was the desired product; however, it was not completely pure after one column. Recolumning in 10% Et2O/Pentane gave a brown oil product completely pure by 1H NMR (9 mg, 9%) and another fraction still slightly impure (18 mg, 18%).
