実験手順
To a solution of 2-(4-fluorobenzoyl)thiophene (5.09 g, 24.7 mmol) in Et2O (100 mL) was added a solution of LiAlH4 (1M in THF, 30 mL, 30 mmol) and the reaction mixture was stirred overnight. The resulting mixture was cooled to 0° C., poured onto ice, extracted with Et2O, dried (Na2SO4) and concentrated under reduced pressure to give (4-fluorophenyl)-2-thienylmethan-1-ol as a yellow oil. The crude product was used without further purification.
