Reaction Steps

A solution of thiophene (5.71 g, 67.9 mmol) in dry THF (60 mL) was cooled to −78° C. under nitrogen. A solution of n-BuLi (26.0 mL, 2.5 M, 65.0 mmol) was then added dropwise. After addition, the reaction mixture was stirred at −78° C. for additional 1 hour, before a solution of 2-butyloctyliodide (16.0 g, 54.0 mmol) in dry THF (30 mL) was added slowly. This mixture was stirred at −78° C. for 1 hour, and then allowed to warm to room temperature slowly and stirred at room temperature for 38 hours. The reaction mixture was poured into water, and the resulting mixture was extracted with ether. The organic layer was washed with water and brine, dried over MgSO4, and concentrated on a rotary evaporator. The residue was subjected to column chromatography on silica gel with hexane as the eluent, leading to a colorless oil as the product (4.95 g, 36.3%).
