Hydrochloric Acid → HCID 86622738, compound

Participants

Reaction Steps

To a suspension of 2-fluoro-6-(2,2,2-trifluoroethoxy)benzonitrile (2.3 g, 11 mmol, J. Hetelocyclic Chem. 1988, 25, 1173-1177) in toluene (40 mL) was added diisobutylaluminium hydride (1.0 M in toluene, 11 mL, 11 mmol) at −78° C. The mixture was warmed to room temperature and stirred for 16 h. Methanol (3.0 mL) was added to the mixture and the mixture was stirred for 10 min, then 2N hydrochloric acid (6.0 mL) was added to the mixture. After being stirred at room temperature for 1 h, the mixture was extracted with ethyl acetate (50 mL×2) and washed with aq. sodium hydrogencarbonate. The combined extracts were dried over magnesium sulfate and concentrated in vacuo to give a solid. The residual solid was purified by silica gel column chromatography (hexane/ethyl acetate 4:1) to afford 2.2 g (94%) of the title compound as a white solid.
