Tetrabutylammonium Fluoride → 4-[1-hydroxy-2-(1-trityl-1H-imidazol-4-ylmethoxy)ethyl]benzonitrile

Participants

Reaction Steps

1.5 mmol of tetrabutylammonium fluoride (1M solution in tetrahydrofuran) are added to a solution of 1 mmol of 4-[1-(tert-butyldimethylsilanyloxy)-2-(1-trityl-1H-imidazol-4-ylmethoxy)ethyl]benzonitrile in 5 ml of tetrahydrofuran, and the solution is stirred at room temperature for 1 hour. The reaction solution is then diluted with water and extracted with tert-butyl methyl ether (2×). The combined organic phases are dried with sodium sulphate and evaporated. The title compound is identified from the residue on the basis of the Rf by flash chromatography (SiO2 60F).
