Reaction Steps

Benzyl bromide (25.65 g, 150 mmol) was added dropwise over 8 h to a suspension of magnesium (3.6 g, 150 mmol) in ether (75 ml) dissolved in ether (30 ml). The resulting mixture was cooled to -10° C. 3-thiophenecarboxaldehyde in ether (45 ml) over 30 min was then added and the resultant reaction mixture was stirred at room temperature for 6 h. This was cooled to 0° C. and the reaction mixture was decomposed by addition of 0.1N HCl. The ether layer was separated and the aqueous phase was extracted with ethyl acetate (2×50 ml). The combined organic layers was dried over MgSO4 and filtered. Removal of the solvent gave 1-(3-thienyl)phenethyl alcohol (16 g, 78% yield).
