Reaction Steps

2-(1H-imidazol-5-yl)aniline 965 mg, 0.410 mmol) was dissolved in acetic acid (2 mL) and benzaldehyde (43 mg, 0.410 mmol) was added. The reaction was stirred for 1 h at room temperature, diluted with 30 mL ethyl acetate, and extracted with 5% HCl (56 mL from 50 mL water+6 mL 12N HCl). The aqueous layer was basified with K2CO3 (add solid portionwise until PH=7), then extracted with ethyl acetate (30 mL×2). The organic layer was evaporated under reduced pressure and the residue was separated by column chromatography to afford the desired product (9 mg, 0.036 mmol, 9%). 1H NMR (MeOH-d4): 7.11-7.25 (m, 3H), 7.41-7.48 (m, 2H), 7.61-7.67 (m, 2H), 7.78 (s, 1H), 8.32 (s, 1H), 8.39 (s, 1H), 8.83 (s, 1H).
