Participants

Reaction Steps

(4-tert-butylphenyl) ethane 1,2 diol (0.5 g, 2.57 mmol) is dissolved in DMF in a 25 ml round bottom flask and to this were added imidazole(0.210 g, 3.09 mmol) and tert-butyldimethylsilyl chloride (0.46 g, 3.09 mmol). The mixture is stirred for 6 hours after which it is extracted in dichloromethane and the organic layer washed with water and dried. Purification by flash chromatography (silica gel; ethyl acetate/hexanes) affords the above mentioned product.
