YieldReaction ConditionsOperation in experiment
65% A solution of BuLi (7.0 mL, 1.6 M in hexane) was added to a solution of 2,3, 5- tribromothiophene (3.2 g, 10 mmol) in ether (100 mL) at-78 C. The resulting mixture was stirred at-78 C for 30 min. N-Methoxy, N-methylactamide (1.2 g, 1.2 eq. ) was added dropwise. The resulting reaction mixture was stirred at-78 C for 30 min, and warmed up to 25 C. Ice cold water and saturated ammonium chloride aqueous solution were added. The organic layer was separated, dried (Na2SO4), and concentrated. The residue was purified by flash column chromatography on silica gel (hexane/EtOAc 9: 1 to 3: 1) to give 1.84 g of titled compound as the light yellow solid (65%).

YieldReaction ConditionsOperation in experiment
28% Compound 25-3 (0444) 25-2 (9.5 g, 30 mmol) was dissolved in anhydrous THF (100 mL) and cooled to -78 C. To the above solution was added dropwise n-BuLi (8 mL, 21 mmol) for 30 min and stirred for 30 min. 25-1 was added dropwise at -78 C., stirred for 30 min and allowed to warm to rt before quenching with saturated ammonium chloride. The organic phase was separated and washed with brine, dried with anhydrous Na2SO4, filtered and concentrated to afford yellow oil, which was purified by column chromatography (elution: PE/EA=10/1) afford 25-3 as a yellow solid (2.3 g, 28%).
