Imidazole → HCID 68193314, compound

Participants

Reaction Steps

(2S)-1-(4′-Bromobiphenyl-4-yl)propan-2-ol (0.23 g, 0.79 mmol) and imidazole (0.11 g, 1.6 mmol) were dissolved in N,N-dimethylformamide (5 mL), and tert-butyldimethylchlorosilane (0.24 g, 1.6 mmol) was added under a nitrogen atmosphere, followed by stirring at room temperature for 1 hour. Diethyl ether was added to the reaction solution, followed by sequential washing with water and hydrochloric acid (1 M). After the solvent was distilled off under reduced pressure, the resulting residue was purified by chromatography on a silica gel column (Moritex Corporation, elution solvent: hexane/ethyl acetate), and a fraction corresponding to the Rf value=0.80 (hexane/ethyl acetate=10/1) by thin layer chromatography was concentrated under reduced pressure to afford the title compound (0.25 g, 0.62 mmol) as a white solid (yield 78%).
