Reaction Steps

Sodium hydride (0.41 g, 20 mmol) was added to a solution of 2-thiophene methanol (2.0 g, 18 mmol) in THF (20 ml) at −40° C. The reaction was stirred at −40° C. for 25 min., then neat benzylbromide (3.6 g, 20 mmol) was added by syringe. The solution was stirred at −40° C. for 0.5 hr, then at room temperature for 1 hr. The THF was evaporated off and the remaining residue was taken up in ether (˜50 ml). The organic solution was washed with water (1×10 ml), brine (1×10 ml) and dried over MgSO4. Evaporation of solvents left an oil which was purified by column chromatography using 1% ether-hexanes to give 2.6 g of the thiophene as a pale yellow oil (78% yield).
