Reaction Steps
The synthesis was performed with reference to the known literature (International Patent Publication WO2000/75139). N,N-Dimethylformamide (2.0 mL) cooled to 0° C. was added dropwise with phosphorus oxychloride (0.54 g, 3.5 mmol), and then the mixture was stirred for 15 minutes. Then, the mixture was added with a solution of N-[(1H-indol-5-yl)methyl]acetamide (0.60 g, 3.2 mmol) in N,N-dimethylformamide (4.0 mL), and then the mixture was stirred overnight at room temperature. The reaction mixture was added with ethyl acetate, and then the organic layer was washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was subjected to silica gel column chromatography (eluted with chloroform/methanol (90:10)) to obtain a solid containing the objective substance. This solid was washed with ethyl acetate to obtain N-[(3-formyl-1H-indol-5-yl)methyl]acetamide (0.12 g, 17%).
