Reaction Conditions

Reaction Steps

A solution, cooled to 0° C., of 6.81 g of 3,4-dimethylbenzyl alcohol and 11.62 ml of N,N,N′,N′-tetramethyl-ethylenediamine in 150 ml of pentane was treated with 62.5 ml of n-butyllithium solution (1.6M in hexane). The reaction mixture was boiled at reflux for 11 hrs. Then, 12.69 g of iodine in 50 ml of THF were added dropwise at −30° C. The mixture was stirred for 15 min. at −30° C. and then left to warm to room temperature. The reaction mixture was added to 100 ml of 10% sulphuric acid. The crude product was isolated by extraction and purified by chromatography on silica gel. There were obtained 2.95 g of (2-iodo-4,5-dimethyl-phenyl)-methanol as a light yellow solid.
