Hydrochloric Acid → HCID 59384155, compound

Participants

Reaction Steps

To a solution of 0.81 g (2.2 mmol) of ethyl 1-(3-ethoxyphenyl)-2-(2-fluoro-4-methylphenyl)-1H-imidazole-4-carboxylate in 10 mL of tetrahydrofuran, 5 mL of water and 5 mL of methanol was added 1.0 mL (5.0 mmol) of 5.0 M NaOH solution. The reaction mixture was stirred at ambient temperature overnight. Hydrochloric acid (2.0 M) was then added to neutralize the reaction mixture. After removal of the organic solvents in vacuo, dichloromethane (20 mL) was added and the organic layer was separated. The aqueous layer was extracted with dichloromethane (10 mL), and the combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to yield the title compound as a yellow foam. LC/MS 341.1 (M+1).
