Acetyl chloride → HCID 44467589, compound

Participants

Reaction Steps

To a stirred solution of 4-(5-phenyl-1H-imidazol-1-yl)butan-1-amine (0.278 mmol) in THF (3 mL) at 0° C. was added acetyl chloride (0.306 mmol) drop wise and the resulting white suspension was allowed to warm to rt and stir for 5 h. Saturated NaHCO3 (2 mL) was added and the aqueous phase was extracted with EtOAc (3×10 mL). The combined organic layers were washed with brine, dried (Na2SO4) and concentrated in vacuo to afford a yellowish oil. Preparative thin layer chromatography afforded the pure product as colorless oil (30 mg, 43% yield). 1H NMR: 1.36 (m, 2H), 1.60 (m, 2H), 1.91 (s, 3H), 2.38 (br s, 1H), 3.12 (m, 2H), 4.00 (t, 2H, J=7.1 Hz), 5.80 (br s, 1H), 7.04 (s, 1H), 7.32-7.46 (m, 5H), 7.55 (s, 1H).
