6-Nitroveratraldehyde → HCID 178487640, 화합물

4,5-Dimethoxy-2-nitrobenzaldehyde (1.52 g, 7.19 mmol), 353.0 mg (6.07 mmol) of potassium fluoride, and 134.8 mg (0.59 mmol) of benzyltriethylammonium chloride were added to a solution of 1.51 g (5.97 mmol) of phenylthio(trimethylsilyl)methyl isothiocyanate, synthesized according to a document (J. Chem. Soc., Perkin Trans 1 1984, 435.), in acetonitrile (36 ml), and the mixture was stirred at room temperature overnight. The solvent was removed from the reaction solution by distillation, and the water and chloroform were then added to the residue. The aqueous layer was extracted with chloroform. The organic layer was washed with saturated brine and was then dried over anhydrous sodium sulfate. The solvent was removed by distillation. The residue was purified by column chromatography on silica gel (n-hexane:ethyl acetate=5:1→1:1) to give 302.4 mg (yield 18%) of the title compound.
