Hydrochloric Acid → 1-(4-Cyano-3-fluorobenzyl)-5-(hydroxymethyl)imidazole

Participants

Reaction Steps

To a solution of 5-(acetoxymethyl)-1-(4-cyano-3-fluorobenzyl)imidazole, as described above in Step E, (19.8 g, 72.5 mmol) in 5:1 THF/water (430 mL) at ambient temperature was added lithium hydroxide monohydrate (3.33 g, 79.4 mmol). After 4 hrs, the solution was adjusted to pH 7 with 1.0 N hydrochloric acid and concentrated in vacuo. The residue was concentrated from toluene in vacuo (3×100 mL) to give the titled product as a pale solid.
