Trifluoroacetic acid → HCID 178442436, compound

Participants

Reaction Steps

Trifluoroacetic acid (1 mL) was added to neat tert-butyl 4-(2,2-dimethylbutyl)-2-{2-[4-(5-fluoropyridin-2-yl)phenyl]-1-[(methylsulfonyl)amino]ethyl}-1H-imidazole-1-carboxylate. After stirring at ambient temperature for 1 h, the reaction mixture was concentrated in vacuo. The residue was partitioned between ethyl acetate and 10% aqueous sodium hydroxide. The aqueous phase was extracted with ethyl acetate. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo. Preparatory plate chromatography eluting with 100% ethyl acetate afforded the title compound. (M+H) found: 445.
