Participants

Reaction Steps

To a stirred solution of 2-(hydroxymethyl)-5-(3'-bromophenyl)thiophene (1.08 G; 4 mM) and triethylamine (1.4 mL; 10 mM) in 20 ml of methylene chloride at R.T. was added t-butyldimethylchlorosilane (1.5 g; 10 mM). This mixture was stirred overnight, diluted with 30 ml of ethyl acetate, washed with 2×15 ml of sat'd. sodium chloride solution, and dried over anhyd. magnesium sulfate. Solvent was removed to give a residue, which was purified on silica gel with ether: petroleum ether (1:20) as solvent mixture. Eluate was distilled to give 0.99 g of 2-(t-butyldimethylsilyloxymethyl)-5-(3'bromophenyl)thiophene as colorless liquid boiling at 167°-170°/~0.2 mm.
