実験手順

A mixture of 1-amino-3-(3,4-dimethoxyphenyl)-3-methylbutan-2-one hydrochloride (210 mg, 0.77 mmol), 4-fluorophenyl isothiocyanate (141 mg, 0.92 mmol), and Et3N (0.16 mL, 1.15 mmol) in benzene (7 mL, anhyd) was refluxed for 8 h. The volatiles were removed under reduced pressure. The residue was combined with acetic acid (5 mL) and heated at reflux 4 h. After concentration, the crude product was purified by flash chromatography to provide 5-(2-(3,4-dimethoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole-2(3H)-thione (260 mg, 91%). 1H NMR (400 MHz, CDCl3) δ 10.35 (s, 1H), 6.87 (t, 2H), 6.80 (d, 1H), 6.67 (d, 1H), 6.62-6.59 (m, 2H), 6.48 (d, 1H), 6.46 (s, 1H), 3.87 (s, 3H), 3.75 (s, 3H), 1.44 (s, 6H).
