Reference Example 27 Synthesis of ethyl 2-(2-formyl-1H-imidazol-1-yl)acetate (0418) (0419) Potassium carbonate (1.44 g, 10.4 mmol), ethyl chloroacetate (0.585 mL, 5.46 mmol), and potassium iodide (0.864 g, 5.20 mmol) were added to a solution of 1H-imidazole-2-carbaldehyde (0.500 g, 5.20 mmol) in N,N-dimethylformamide (10.0 mL) at room temperature, the temperature of the reaction liquid was raised to 90 C., and the reaction liquid was stirred for 4 hours. Distilled water was added to the reaction liquid, and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with a 10% aqueous solution of sodium chloride, and then dried over anhydrous sodium sulfate and filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, chloroform/methanol) to obtain ethyl 2-(2-formyl-1H-imidazol-1-yl)acetate (0.269 g, 1.48 mmol, 28%) as a yellow oil. (0420) 1H-NMR (400 MHz, CDCl3) delta: 1.29 (3H, t, J=7.2 Hz), 4.25 (2H, q, J=7.2 Hz), 5.14 (2H, s), 7.15 (1H, brs), 7.33 (1H, s), 9.79-9.91 (1H, m). (0421) ESI-MS: m/z=183 (M+H)+.
